摘要:
A domino SRAM array restore pulse generation system launches the work decode line by the same local clock as the restore pulse, thus eliminating any race issues with the word line select. This system allows the global bit select (or column select) to have fast activation by releasing the reset signal (with the earliest arriving array clock, ck1), while guaranteeing almost perfect tracking with the bit decode system. This allows for the widest possible write window; earliest release of the pre-charge in the global column select, and resetting only after the bit decode system is deactivated.
