RAMSRAM都是存在于计算机内部的存储器类型。它们是一种存在于计算机系统中的易失性存储器。 RAM 和 SRAM 是缩写,分别扩展为随机存取存储器和静态随机存取存储器。

1. 随机存取存储器(RAM):
它是一种易失性存储器,因为它在断电后会丢失数据。它在有限的时间内包含数据和进程,直到 CPU 需要它为止。读取和写入操作在 RAM 中进行得非常快。它被称为随机存取存储器,因为它提供了提供有关在单元格处相交的行和列的信息的功能。

2. 静态随机存取存储器(SRAM):
它是一种 RAM。它使用具有 6 个晶体管的 CMOS 技术。 SRAM 在待机、读取和写入状态下运行。它本质上是同步的。

这两个术语之间的主要区别在于随机存取存储器 (RAM) 包含静态随机存取存储器 (SRAM),或者我们也可以说 RAM 是 SRAM 的超级集。

RAM和SRAM的区别:

S.No. RAM SRAM
1. RAM is a type of volatile memory that loses data when power is disconnected. The SRAM is a type of RAM, that is synchronous and is formed from internal latches.
2. It is overall more costly than SRAM because it contains both Static RAM (SRAM) and Dynamic RAM (DRAM). It is less costly than RAM.
3. It is used by OS and application software. It is used by high-speed registers, caches and smaller memory banks (e.g. frame buffer).
4. Examples of RAM comprise Mac computers that have between 128 and 512 MB of RAM. Examples of SRAM comprise IBM Microelectronics’ PC compatible SRAMS that are sold in 52 pin PLCC or 100 pin TQFP packages.
5. It may or may not use busses. It does not require busses.
6. It is the most basic form of computer memory that helps the fast startup and fast shutdown of a computer. It is an integrated chip that is quick and easy to control.
7. It is contains the Static RAM (SRAM) and Dynamic RAM (DRAM). It is contained inside a RAM.
8. Capacitors or Transistors are used to store data in RAM. Transistors are used to store information in SRAM.
9. Transistors are used due to which refreshing is required at regular intervals. Capacitors are not used due to which no refreshing is required.
10. It is a combination of low and high density devices. It is a low-density device.
