ABSTRACT:
A semiconductor memory device wherein, in order to control the current consumed in a column address counter and latch block in a read operation, delay units disposed in the column address counter and latch block perform a shifting operation according to a signal CASP6, which is enabled in the write and read operations, and a signal WT6RD5Z, which is enabled in the write operation and disabled in the read operation. Accordingly, unnecessary current consumed in the read operation can be reduced.
