System Memory Review Questions

1) Define RAM, ROM, EDO, FPM, DDR, SDRAM, SRAM, RDRAM.

2) Where might flash memory be found on the system board?

3) How many pins are on a SIMM (2 types)?

4) What is the data path bit architecture of a SIMM?

5) What are the two technologies (type of memory) used by SIMM?

6) What does 5-3-3-3 Burst mode timing indicate as to the pulses of the processor clock accessing memory?

7) What is the nanosecond? What would 8 nanoseconds be equivalent to in terms of memory bus speed frequency?

8) How many pins are on a DIMM?

9) What is the data path bit architecture of a DIMM?

11) What type of SDRAM would you install on a motherboard that supports a 100MHz memory bus?

12) What type of SDRAM would you install on a motherboard that supports a 133 MHz memory bus?

13) Why is SRAM faster than SDRAM? What is SRAM specifically used for in the system?

14) How is data transferred during the clock pulse of DDR memory?

15) In what type of system would you probably see ECC SDRAM?
