Memory

Question 1

More complex and less dense
Faster and requires less power
Requires periodic power to maintain the state of memory
Typically use in cache memory

Answer 1

Static RAM (SRAM)

Question 2

Simple to implement
Very high density
Inexpensive
Must continually supply power to the transistor; when the power is turned off, the data is lost

Answer 2

Dynamic RAM (DRAM)

Question 3

Synchronized with the system clock and accept 64-bit words
Two consecutive data sets per bus clock cycle
2.5 volts; bus freq. between 100-200MHz
184 pins

Answer 3

DDR

Question 4

Four consecutive 64-bit words per bus clock cycle
Includes buffer between the data bus and the memory
1.8votls;
