256Mbit Mobile FCRAM
Overview
MB82DDS08314A Package View
Fujitsu is now offering 3 types of 256Mbit Mobile FCRAM featuring high-speed data transfer.
MB82DDS08314A adopts double data rate (DDR) burst mode and it is capable of high-speed data transfer performance up to max.
1 Gbyte/sec. In the DDR burst mode, twice data read-out per one clock period are executed and thus high-speed data transfer
is achieved.
MB82DBS08314A and MB82DBS16164A adopt the conventional single data rate (SDR) burst mode and provide an ideal solution for
customers who need large RAM density with an existing SDR pseudo SRAM interface.
