A one MB cache subsystem prototype with 2GHz embedded DRAMs in 45nm SOI CMOS

We present a 1 MB cache subsystem that integrates 2 GHz embedded DRAM macros, charge pump circuits, a 4 Kb one-time-programmable ROM, clock multipliers, and built-in self test circuitry, having a 36.5 GB/s peak system data-rate. The eDRAM employs a programmable pipeline, achieving a 1.8 ns latency.
