Abstract: The present invention discloses an amendable static RAM, which can be modified from a high-priced corrupt 32K.times.36 one to a correctly functioning 32K.times.32 one. In each memory block, at least a common sense amplifier is employed as an amendable local sense amplifier. Each amendable local sense amplifier is coupled to a corresponding amendable common sense amplifier and by a switching circuit following the amendable common sense amplifier to all I/O buffers in the same memory block. When the static RAM works well and does not require amendment, the switching circuit is set to a normal condition that the amendable common sense amplifier is coupled to a corresponding amendable I/O buffers. When the static RAM is corrupt and requires modification, the switching circuit is set to an amendable condition wherein the amendable common sense amplifier is coupled to a normal I/O buffer corresponding to the corrupt memory column.
