Chapter 6, Problem 1RETC

Explanation of Solution

Memory:

• Memory is a physical storage device where any information that are needs to be accessed can be stored either permanently or temporary.
• There are two kinds of memory and they are:
  • RAM(Random Access Memory)
    • It is read write memory.
    • The data are stored temporary and they are volatile in nature.
    • The contents of the RAM can be modified.
  • ROM(Read Only Memory)
    • It is read only memory
    • The data are stored permanently and they are non-volatile in nature.
    • The data cannot be modified in ROM because it is read only.

Two type of RAM:

There are two type of RAM namely:

• SRAM(static Random Access Memory)
  • It is the fastest memory which requires power to retain the content that is present in it.
• DRAM(Dynamic Random Access Memory)
  • It is slower memory where it requires being refreshed again and again to retain its data.

Fastest Memory:

The memory SRAM is considered as the fastest memory because it does not need to be refreshed again and again to retain its data; it requires only continuous power supply to retain its data.

Therefore, SRAM is considered as the fastest RAM.
