90% of SRAM manufacturers now make Pseudo SRAM

According to Semico Research, Pseudo SRAM (PSRAM) is gaining ground. PSRAM has a one-transistor DRAM cell, as opposed to the typical six-transistor SRAM cell.

According to Semico Research, Pseudo SRAM (PSRAM) is gaining ground. PSRAM has a one-transistor DRAM cell, as opposed to the typical six-transistor SRAM cell. The DRAM architecture gives PSRAM some strong advantages over low-power 6T SRAM, namely smaller size and competitive pricing. Manufacturers that account for 90% of the total SRAM market now make PSRAM. The company's forecast is still on target for 1.2 bln unit shipments for 2005, $2.7 bln in revenues, and an aggregate ASP down $.21 from 2004.
