2 GHz 2 Mb 2T Gain Cell Memory Macro With 128 GBytes/sec Bandwidth in a 65 nm Logic Process Technology

We present 2 Mb 2T PMOS gain cell macro on 65 nm logic process that has high bandwidth of 128 GBytes/sec, fast cycle time of 2 ns and 6-clock cycles access time at 2 GHz. Macro features a full-rate pipelined architecture, ground precharge bitline, non-destructive read-out, partial write support and 128-row refresh to tolerate short refresh time. Cell is 2X denser than SRAM and is voltage compatible with logic.
