Abstract
A memory control circuitcontrols an operation of reading stored data from a memory cellconnected to a word line WL and a bit line BL based on an address Address including a row address Ax and a column address Ay. When the address Address includes redundancy addresses Pto Pdesignating a word line WLa or a bit line BLc connected to a specific memory cell Cc, redundancy decoders-to-replace the specific memory cell Cc with a redundancy memory cell RCc connected to redundancy word lines RWLand RWLor redundancy bit lines RBLand RBL. Redundancy address latch circuits-to-respectively hold the redundancy addresses Pto P, and erase the held redundancy addresses Pto Pbased on a reset signal RS inputted from the memory control circuit
