RAM (Random Access Memory), we all know that it is one of the important hardware device. Whatever we work on the PC it is running on RAM. When we boot the computer, the operating system which is stored in the secondary memory or Hard Disk Drive (HDD) first load in the RAM. Because of this process our PC takes some time for operate. But it is meter of storing but did you ever think that how the RAM looks?? .
Practical approach is the best way to learn new thing. Random Access Memory has some types which we are going to learn below:
- SRAM (Static Random Access Memory)
The latching circuit has three types :
1. SR NOR latch
2. SR NAND latch
3. JK latch
(1.1 Bistable SR NOR Latching Circuit)
SRAM is a type of semiconductor memory where the word sttic indictes that, unlike dynamic random access memory.SRAM uses multiple transistors, typically four to six, for each memory cell but doesn't have a capacitor in each cell. It is used primarily for cache.
Static Random Access Memory (SRAM) is a type of RAM used in various electronic applications including toys, automobiles, digital devices and computers. Static RAM or SRAM only holds its contents while power is applied.
SRAM is more expensive, faster and more power-efficient than DRAM for most uses. However, its internal structure also makes it less dense, and therefore a less ideal candidate for the main memory inside personal computers. Instead, SRAM is utilized for critical, secondary uses such as fast cache memory for central processing units (CPUs).
Examples:
- Modem Routers
- Printers
- Digital Cameras
- Compact Disk (CD)
- Digital Versatile Disk (DVD)
- Toys with electronic interface
