Abstract

PURPOSE: To collectively erase one or more selected blocks to shorten the erase time by providing a word line decoding circuit with latch circuits which can be selectively set by a block address.
CONSTITUTION: A word line decoding circuit 101 is provided with latch circuits 102, 103, and 104. The block address is selected by an address decoder 114. When blocks 111 and 112 will be erased, latch circuits 102 and 103 are set by the block address, and blocks 111 and 112 are simultaneously erased with one erase operation. The block 113 is not erased in this case because the latch circuit 104 is not set, and plural blocks are selectively erased. Though two blocks are collectively erased, one or more arbitrary blocks can be selectively and collectively erased.
