What is the difference between static RAM and dynamic RAM in a computer?

1. There are two types of ram, namely: static memory and dynamic memory. The characteristics are: high-speed reading and writing points, and veraticity. Classification Static memory Compared with DRAM, SRAM is faster and has a shorter access time. The storage unit of SRAM is called "trigger" and consists of two complementary bistable memory.

2. Static RAM relies on bi-steady-state triggers to remember information; dynamic RAM relies on gate-level capacitors in MOS circuits to remember information. Because the charge on the capacitor will leak and need to be replenished regularly, the dynamic RAM needs to set up a refresh circuit.

3. [Answer]: Dynamic RAM uses parasitic capacitors to store data, and static RAM does not use parasitic capacitors to store data.The peripheral circuit of the dynamic RAM storage array refreshes RAM at certain intervals to supplement the charge to the parasitic capacitor of the storage data.

4. The trigger of the memory unit consists of 4 or 6 transistors and some lines, but it never needs to be refreshed. This makes static RAM much faster than dynamic RAM.

5. Because the charge on the capacitor will leak and needs to be replenished regularly, the dynamic RAM needs to set up a refresh circuit. However, dynamic RAM has higher integration and lower power consumption than static RAM, so the cost is also low, which is suitable for large-capacity memory. Therefore, the main memory usually uses dynamic RAM, while the high-speed buffer memory (Cache) uses static RAM.

What is the maximum RAM of the computer now?

then the maximum memory = 533*32/8=2132Mhz is about 2G, and the operating system bits should correspond to the processor bits. The operating system bits cannot be greater than the processor bits. 64 means that the operating system cannot be installed in the 32-bit CPU. Up. At the same time, the maximum memory is the largest of the two.

In theory, the maximum running memory supported by the computer is 128G, and the maximum running memory of a 32-bit operating system is only 25GB. How much memory the computer can use depends on the motherboard.

A memory stick is up to 128G. A memory stick is a computer component that the CPU can address through the bus and perform read and write operations. The memory stick used to be an extension of the main memory in the history of personal computers. With the continuous updating of computer software and hardware technology, the memory bar has become the whole of read and write memory.

This depends on what kind of brand it looks like. I think the current tablet should have 256f. This one should be so big. Anyway, it won't be very small. This should be quite good. The following is the extension information about memory.

Memory (RAM): 64GB or more of high-speed DDR4 memory, which can provide faster data access speed and higher multitasking power.

A single 16G, the ram of the computer is the memory of the computer. You can buy and install it by yourself.

What is memory

1. Memory is a kind of data transit "warehouse", and in the process of frequent transit, what if the data is wrong? And ECC is a data inspection mechanism. ECC can not only judge the correctness of the data, but also correct most errors. This kind of memory is generally not used in ordinary PCs, and they are generally used in high-end server computers.

2. Memory is an internal memory that directly exchanges data with the CPU. It can be read and written at any time and is very fast, as a temporary data storage medium for the operating system or other running programs. Memory is used to load a variety of programs and data for the CPU to run and use directly.

3. Memory usually refers to the RAM in the computer system. RAM is a bit like the blackboard in the classroom. In class, the teacher keeps writing things on the blackboard and erases them all after class. RAM requires continuous power supply every moment, otherwise the data will be lost.

4. Memory is a component used to store programs and data. For computers, only with memory can it have a memory function to ensure normal operation.

5. Memory is the place where programs and data are stored. For example, when we use WPS to process documents, when you type characters on the keyboard, it is stored in memory. When you choose to save the disk, the data in the memory will be stored in the hard (magnetic) disk.

The internal memory of the computer refers to RAM and ROM. What are RAN and ROM?

ROM is the abbreviation of Read-Only Memory, which is a solid-state semiconductor memory that can only read pre-stored data. Its characteristic is that once the data is stored, it cannot be changed or deleted. It is usually used in electronic or computer systems that do not need to change the data frequently, and the data will not disappear due to power off.

The internal memory of the computer is divided into (RAM) and (ROM), and the memory strip is often referred to as (RAM). Memory is divided into random memory (RAM), also known as read and write memory; Read Only Memory (ROM).

ROM and RAM are two models of in-computer memory. ROM represents read-only memory, that is, it can only read information, not write information. After the computer is turned off, the information inside is still saved, and it is generally used to store fixed system software and word libraries.

RAM refers to random access memory, and ROM refers to read-only memory. RAM random access memory, abbreviation: RAM, also known as main memory, is an internal memory that directly exchanges data with the CPU.

May I ask about the system program memory? What is the difference between user program memory, RAM and ROM? There is...

1. Different structure: RAM refers to random storage memory. ROM belongs to read-only memory, which is a kind of solid-state semiconductor memory.

2. Different properties RAM is a random access memory, also known as main memory, which is an internal memory that directly exchanges data with the CPU. RAM is random storage memory. This kind of memory will lose its storage content when the power is cut off, so it is mainly used to store programs that have been used for a short time.

3. The main difference between rom and ram is that they have different properties, different characteristics and different applications. Different properties. ROM is a read-only memory, which works in a non-destructive read-out method, and can only read out information that cannot be written to. RAM is a random access memory, also known as main memory, which is an internal memory that directly exchanges data with the CPU.

4. The difference between RAM and ROM is as follows: ROM and RAM are both a storage technology, but the principle of the two is different. RAM is a random storage, and the data will not be saved when the power is lost, while ROM can still save the original data in the event of a power loss. ROM and RAM both refer to semiconductor memory.

5. ROM is in read-only mode, so the system uses it to avoid accidental deletion or virus infection; while RAM is readable and writable, and users should use it in ordinary operations.

6. Ram is memory. Just like the memory of the computer. Rom is an internal storage. Just like the hard disk of a computer. That is to say. Ram is related to how much software you can run. Rom is related to how much software you can install.

What is the running memory RAM of the mobile phone and what is it used for?

1. ram (random access memory) random memory, whose contents can be taken out or stored at will as needed, and the access speed has nothing to do with the location of the storage unit. This kind of memory will lose its storage content when the power is cut off, so it is mainly used to store programs that have been used for a short time.

2. RAM is running memory, abbreviated as operating memory, which is a component used to temporarily save data in a mobile phone, which is equivalent to a memory bar in a computer. It can be read and written at any time and is fast, usually as a temporary data storage medium for the operating system or other running programs.

3. RAM is the running memory, which has been occupied since the mobile phone is turned on, and every application will occupy the running memory.ROM is the abbreviation of ROM image (read-only memory image), which is often used in the circle of mobile phone customized system players.

4. Running memory is RAM. Mobile phone memory is ROM. Large storage refers to the size of the ROM capacity of the machine, which is not RAM. SD card capacity refers to the capacity of your external expansion card.

5. Simply put, the RAM of a mobile phone is memory, which is the same function as our computer memory.
