PSRAM (Pseudo SRAM): Mobile FCRAM
Mobile FCRAM is the PSRAM (Pseudo SRAM) developed for cellular phones. Mobile FCRAM interface is based on the asynchronous SRAM and supports page mode and synchronous burst mode for high-speed read and write operation with low power consumption. The Mobile FCRAMs are ideal for general mobile applications such as smart phone, PDA, portable media player(PMP), and portable games.
