Abstract:
In general, each parallel test operation on Static Random Access Memory (SRAM) cells is a test operation performed on a block of the SRAM cells in parallel, or simultaneously. In one embodiment, the SRAM cells are arranged into multiple rows and multiple columns where the columns are further arranged into one or more column groups. The block of the SRAM cells for each parallel test operation includes SRAM cells in two or more of the rows, SRAM cells in two or more columns in the same column group, or both SRAM cells in two or more rows and SRAM cells in two or more columns in the same column group.
