Static RAM (SRAM) and Dynamic RAM (DRAM) (Part-2)

• Static Random Access Memory (SRAM)

SRAM (static RAM) is random access memory (RAM) that retains data bits in its memory as long as power is being supplied. Unlike dynamic RAM (DRAM), which stores bits in cells consisting of a capacitor and a transistor

• SRAM does not have to be periodically refreshed. 
• Static RAM provides faster access to data and is more expensive than DRAM. S
• RAM is used for a computer's cache memory and as part of the random access memory digital-to-analog converter on a video card.

• Dynamic Random Access Memory (DRAM)

Dynamic random access memory (DRAM) is a type of memory that is typically used for data or program code that a computer processor needs to function. DRAM is a common type of random access memory (RAM) used in personal computers (PCs), workstations and servers.

• Random access allows the PC processor to access any part of the memory directly rather than having to proceed sequentially from a starting place. 
• RAM is located close to a computer’s processor and enables faster access to data than storage media such as hard disk drives and solid-state drives.
