CellularRAM™
Low Power SRAM Performance at DRAM Cost.
CellularRAM ™ is a multi-generation family of low-power pseudo-static RAM (PSRAM) for wireless handsets. It is designed to replace SRAM in next-generation mobile phones and bandwidth demands of future 2.5G and 3G handset designs by providing a high capacity, high bandwidth and power efficient memory solution. Additionally, this technology offers a lower cost/bit ratio than current solutions.
This new type of Pseudo SRAM features a
- SRAM-pin compatibility and
- refresh-free operation and a low-power design.
Available densities:
- 16Mb
- 32Mb
- 64Mb
- 128Mb
Address-Data Multiplexing:
- Non-mux
- AD-mux
Advantages:
- Backward compatible with standard SRAM devices.
- Backward compatible with standard SRAM devices.
- Power consumption comparable to SRAM devices.
- Supporting asynchronous/page modes, as well as an innovative burst interface - that is fully compatible with the low-power Flash interface.
- Performance: asynchronous/page version access time 70ns. CellularRAM™ - with burst access mode burst rate of up to 104 MHz.
- The price/bit ratio of CellularRAM™ is significantly lower than an SRAM device.
