8 Mb to 128 Mb High-Speed CMOS PSRAMs

Alliance Memory’s devices provide the high bandwidth and the low power necessary to replace SRAMs in portable electronics

Image of Alliance Memory 8 Mb to 128 Mb High-Speed CMOS PSRAMsAlliance Memory's high-speed CMOS pseudo SRAMs (PSRAMs) combine the most desirable features of SRAMs and DRAMs to provide designers with easy-to-use, low-power, and cost-effective memory solutions. Featuring high-density DRAM cores with SRAM interfaces and on-chip refresh circuits for refresh-free operation, the devices provide the high bandwidth and the low power necessary to replace SRAMs in portable electronics such as mobile phones and PDAs, or to serve as companion chips to burst NOR Flash applications.
