Which of the following types of memory is used for cache memory?
SRAM
DRAM
EDO RAM
SDRAM
Dynamic RAM is a type of RAM that only holds its data if it is continuously accessed by special logic called a refresh circuit
True
False
DRAM has which of these features?
Must be re energized constantly, or it will lose its contents
Need refreshing
Less expensive
All of these
(a) is much faster because they are synchronized to the system clock
(a) allows higher bus speed and requires lower power by running the internal clock at half the speed of the data bus.

Memory cache
Match the following: Types of SRAM
Synchronous SRAM
Faster and more expensive
than asynchronous SRAM
Synchronous SRAM
It requires a clock signal to
validate control signals,
enabling the cache to run in
step with the CPU
Asynchronous SRAM
Does not work in step with
the CPU clock, and is,
therefore, slower than
synchronous SRAM
Asynchronous SRAM
Used for specific application
within CPU
SRAM is more expensive than DRAM.
True
False
Match the following: Advantages and disadvantages of SRAM
Disadvantages
Size - It has a limited amount of storage space.
Disadvantages
Cost - It is more expensive than DRAM.
Advantages
Speed SRAM is faster than DRAM since it has a faster access time.
Advantages
Simplicity - SRAM offers easy to build interfaces in order to access the memory.
Advantages
Durability - SRAM is a type of memory chip that is both quicker and more energy-efficient than DRAM.
