Pseudostatic RAM
1 Mbit pseudostatic RAM module, type TC518129CFWL-80, from Toshiba
Pseudostatic RAM ( PSRAM ) is a type of memory component for computers . Its content is volatile, i.e. the stored information is lost when the operating voltage is switched off.
A PSRAM consists of a DRAM with a built-in control circuit for the necessary refreshing of the memory cells and a circuit for converting the SRAM interface to a DRAM interface. As a result, it combines the advantages of the small area required by the DRAM with the relatively simple control of an SRAM .
Depending on the manufacturer, the product names for the PSRAM are CellularRAM ( Micron Technology ), 1T-SRAM ( MoSys ) and PSiRAM ( Tezzaron Semiconductor , 2003).
