An experimental 512-kB embedded Phase Change Memory (PCM) is developed in a 0.13-μm 1.5-V CMOS technology. Three circuit techniques were developed to apply the previously developed low-power PCM cell to embedded ROM modules. A sense-amplifier-prefetch serial write scheme and a two-step set method achieve 416-kB/s write-throughput at 100-μA cell current. A charge-transfer direct-sense scheme has a 16-bit parallel read access time of 9.9 ns in a memory array drawing 280 μA. A standby voltage control scheme suppresses leakage current in the memory array and enlarges the range of measurable PCM cell resistance from 3 MΩ to 33 MΩ. These circuit techniques realize a low-power embedded PCM. |
