Q

What is the difference between DRAM and SRAM?

A

DRAM is the most common in personal devices and gaming consoles. SRAM is not dynamic and does not need to be refreshed constantly. But SRAM requires a constant flow of power. DRAM is used for things like networking, hardware and PCs. SRAM is used for cache memory in things like printers, routers and digital cameras. DRAM is slower and consumes more power.

Q

What is memory that checks itself?

A

Also known as “Error Correcting Code memory” or ECC memory. A type of memory that includes additional error detection and error correction capabilitites of a computers memory subsytem. Used on critical systems such as VM server, database server, workstations etc.

Q

What is parity memory?

A

Parity RAM can detect corruption in RAM but can not correct it.

17
Q

How does parity RAM work

A

It adds an extra bit for every byte of data stored in memory.
