SRAM

SRAM stands for Static Random Access Memory.Its access time less than 60 nan0seconds.


DRDRAM

DRDRAM stands for Direct Rambus Dynamic Random Access Memory.It is the new type of RAM. It access time 20 times faster than DRAM.

Very good hub. Hopefully a lot of people will read and learn from this. I can't tell you how many people have replied with 500GB when I asked them how many gigs of RAM they're running on their tablet or computer. Voted up.
