DUMMY READ TO PREVENT CROWBAR CURRENT DURING READ-WRITE COLLISIONS IN MEMORY ARRAYS WITH CROSSCOUPLED BITLINE KEEPERS |
摘要 |
Systems and methods for detecting and suppressing crowbar currents in memory arrays. A dummy read is implemented to prevent crowbar currents in the case of simultaneous read-write collisions in a static random access memory (SRAM) array having cross-coupled bitline keepers. When a simultaneous read and write operation to a first entry of the memory array is detected, the read operation to the first entry is suppressed and a dummy read operation to a second entry of the memory array is performed. The write operation to the first entry is allowed to proceed undisturbed. |
