IPC: G11C17/00
Filed: 1995-01-11
Abstract: PURPOSE: To obtain high performance with simple constitution by providing a power source selection means and a buffer for block at every block and sharing a row decoder between blocks. CONSTITUTION: The power source selection means 3-1 to m are provided at every first to m-th blocks to output a first or a second voltage by a selection signal. For instance, when the selection signal is the selection signal of the block accessed at a write time, only the power source selection means of the written block outputs the first voltage, and other output the second voltage. The row decoder 1 or the buffers 2-2 to m for block correspond to respective blocks. The decoder 1 outputs an access signal according to the voltage from the means 3-1. Then, a word line WL is separated at every block, and a high voltage is applied when the word line WL of the block in which a cell Ce to be accessed exists is written, and a low voltage is applied to other lines. Thus, no write operation in a certain block causes disturbance in other block.
