pseudostatic (random-access) memory (PSRAM)
(1) A combinational form of a dynamic RAM that incorporates various refresh and control circuits on-chip (e.g., refresh address counter and multiplexer, interval timer, arbiter). These circuits allow the PSRAM operating characteristics to closely resemble those of an SRAM.
(2) A random-access memory whose internal structure is a dynamic memory with refresh control signals generated internally, in the standby mode, so that it can mimic the function of a static memory.
NOTE In practice, unlike so-called self-refresh DRAMs, PSRAMs have nonmultiplexed address lines and pinouts similar to those of SRAMs.
