Q

What are the characteristics of Dual Inline Memory Modules? (DIMMS)?

A
  1. Printed Circuit Board (PCB) type used as a placeholder for memory chips
  2. Separate electrical contacts on each side of the module
  3. 64-bit data path
  4. Used with various SDRAM memory types (SDR, DDR, DDR2, and DDR3)

Q

For DDR SDRAM (Double Data Rate) memory, every clock cycle you can send double the amount of data opposed to SDR Ram. True or False?

A

True.

  1. Twice as fast as SDR (single data rate)
  2. Twice as much information in exactly the same clock time as SDR memory.

Q

Why is SDRAM (Synchronous Dynamic Random Access Memory) called “Synchronous”?

A

It’s synchronized with the clock that’s inside the computer (the system bus).
