Micron Technology Inc. introduced a new memory device designed for low-density, entry-level mobile handsets. According to the press release, the x16 burst A/D multiplexed pseudo-SRAM (PSRAM) further enables a manufacturers ability to reduce costs within basic-feature handset designs due to additional features incorporated into an already low-cost CellularRAM device.

The enhanced CellularRAM device is designed for low-cost handsets using new single-chip microprocessors produced by controller manufacturers. CellularRAM memory is a high-performance, multigenerational alternative to traditional SRAM.

The x16 burst A/D multiplexed PSRAM features combined address and data pins used for both READ and WRITE functions. With more than a 30 percent pin count reduction, manufacturers can simplify their controller design resulting in an overall reduced system cost, said Micron.

Available in bare die form, the x16 burst A/D multiplexed PSRAM is offered for general customer sampling in 64-, 32- and 16Mb densities. Volume production is expected during the first quarter of 2006 to support emerging market demand for entry-level handsets.
