PRODUCT DESCRIPTION

The SST34HF16x2C/D/S ComboMemory devices integrate either a 1M x16 or 2M x8 CMOS flash memory bank with either a 128K x16/256K x8, 256K x16/512 x8, or 512K x16/1024K x8 CMOS SRAM or pseudo SRAM (PSRAM) memory bank in a multi-chip package (MCP). These devices are fabricated using SST’s proprietary, high-performance CMOS SuperFlash technology incorporating the split-gate cell design and thick-oxide tunneling injector to attain better reliability and manufacturability compared with alternate approaches. The SST34HF16x2C/D/S devices are ideal for applications such as cellular phones, GPS devices, PDAs, and other portable electronic devices in a low power and small form factor system.
