Pseudo SRAM
Pseudo SRAMs (PSRAMs) are memories consisting of a DRAM macro core with a traditional asynchronous SRAM interface. They feature fast access time and low power consumption. Comparing to traditional CMOS SRAM have a higher density, higher speed, smaller die size and DRAM compatible process.
* Status: P - mass production, S - samples, UD - under development, N - not recommended for new design.
