Chapter 4 Ram Vocab

Question 1

What kind of RAM does CPUs use?

Answer 1

Dynamic random access memory (DRAM) as RAM for all PCs

Question 2

Synchronous DRAM (SDRAM)

Answer 2

SDRAM is still DRAM, but it’s synchronous tied to the system clock, just like the CPU or MCC, so the MCC knows knows when data is ready to be grabbed from SDRAM

Question 3

What does DIMM stand for?

Answer 3

Dual inline memory module (DIMM)

Question 4

What is SO-DIMM?

Answer 4

Small outline DIMM (SO-DIMM)

Question 5

Bank

Answer 5

A DIMM in any one of the DIMM slots could fit the 64 bit bus, so each slot was called a bank

Question 6

Double data rate SDRAM (DDR SDRAM)

Answer 6

bacillus copied a proprietary memory solution developed by Rambus, doubling the throughput of SDRAM by making two processes for every clock cycle

184 pin DIMMs

Question 7

Rambus DRAM

Answer 7

RDRAM was initially introduced a a replacement for regular SDRAM. while faster than SDRAM, RDRAM was ultimately rejected by the industry due to delays in development and high prices compared to its predecessor.

Question 8

Extreme memory profile (XMP)

Answer 8

enables power users to overclock their RAM easily, boosting their already fast memory.

AMDs version of XMP is called AMP for AMD Memory profile.

Question 9

Triple-channel memory architecture or quad-channel memory architecture

Answer 9

Works a lot like dual channel, but with 3 or 4 sticks of RAM instead of two.

Question 10

Power management integrated circuit or PMIC and

Answer 10

Cooperation between hardware, bios, and os to reduce power consumption

Question 11

Latency

Answer 11

The delay in RAMs response time
