PSRAM (Pseudo SRAM): Mobile FCRAM
Mobile FCRAM is PSRAM (Pseudo SRAM) that was developed for cellular phones. The Fujitsu Mobile FCRAM interface is based on asynchronous SRAM and supports page mode and synchronous burst mode for high-speed read and write operation with low power consumption. Mobile FCRAMs are ideal for general mobile applications such as smart phones, PDAs, portable media players (PMPs), and portable games.
Mobile FCRAM(PSRAM) Features
- Low Power SRAM Compatible interface
- Asynchronous Operation
- Refresh Free - Large Density
- Offering larger density than conventional SRAM
- 32Mbit and 128Mbit in production now - Low Power Design
- Same or less active power than SRAM
- Very low data retention current compare to regular DRAM
