ABSTRACT:
A semiconductor memory has a plurality of memory arrays, and a plurality of selection circuits. Each of the memory arrays has a plurality of memory blocks. The selection circuits is provided to the memory arrays and is used to independently disable a defective memory block and select a normal memory block in the memory array. Therefore, the semiconductor memory enables to increase the number of partial good memories (half good memories: half capacity memory), and to increase a product yield.
