Jack Butler’s Memory

What size data path would you expect to find on a dual inline memory module?

A) 16 bits

B) 32 bits

C) 64 bits

D) 128 bits

E) 220, 221, whatever it takes.

The answer: C) 64 bits

The standard size data path for a DIMM is 64 bits. Since DDR/DDR2/DDR3 SDRAM uses DIMMs, when you calculate the total amount of throughput you use the 64 bit multiplier as part of the formula.

There have been many different memory slot formats through the years. In this video, you’ll learn the difference between SIMMs, RIMMs, DIMMs, and SO-DIMMs.
