- Psedostatic RAMs are not truly static, because (in some cases), they can
- be "busy" refreshing while you want to access data. Also, they tend to
- be slower than true static RAM.
-
- As for power, they do pretty well, but I wouldn't expect one to retain
- data at 2V and a few microamps.
-
- If you're building your own project, and access time is not an issue, then
- PS RAM might be a convenient way to go (saves a DRAM controller). However,
- for commercial applications, there's only a narrow range of uses that justifies
- the PS price (vs. dynamic).
