RAMSRAM都是计算机内部内存的类型。它们是计算机系统中存在的一种易失性存储器。 RAM和SRAM是分别扩展为随机存取存储器和静态随机存取存储器的缩写。

1.随机存取存储器(RAM):
这是一种易失性存储器,因为在断开电源后会丢失数据。它只在有限的时间内包含数据和进程,直到CPU需要为止。读和写操作非常迅速地进入RAM。由于它提供了有关在单元格处相交的行和列的信息的便利,因此它被称为随机存取存储器。

2.静态随机存取存储器(SRAM):
它是RAM的一种。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。

术语之间的主要区别是随机存取存储器(RAM)包含静态随机存取存储器(SRAM),或者我们也可以说RAM是SRAM的超集。

RAM和SRAM之间的区别:

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.
