FullFlex? Synchronous DDR Dual-Port SRAM

The FullFlex, Dual-Port SRAM families consist of 4-Mbit, 9-Mbit, 18-Mbit, and 36-Mbit synchronous, true dual-port static RAMs that are high-speed, low-power 1.8V/1.5V CMOS. Two ports are provided, allowing the array to be accessed simulta- neously. Simultaneous access to a location triggers determin- istic access control. For FullFlex72, these ports CAN operate independently in DDR mode with 36-bit bus widths or in SDR mode with 72-bit bus widths. For FullFlex36 and FullFlex18, the ports operate in DDR mode only. Each port CAN be independently configured for two pipelined stages for SDR mode or 2.5 stages in DDR mode. Each port CAN also be configured to operate in pipelined or flow-through mode in SDR mode.
