Abstract
PURPOSE: To remove an intermittent error of two-bit error data by making a reread by making use of the two-bit error detecting function of an error detecting correction circuit.
CONSTITUTION: When error detecting correction circuit 3 detects a two-bit error on signal line 102, an address corresponding to this two-bit error data is selected by address selector circuit 6 under the control of signal line 103 since this address is stored in address stand-by register 5, thereby realizing a reread from memory circuit 1. In this way, at most one bit of the two-bit error of data read out firstly is removed and when the other is caused by an intermittent read error, this intermittent error can be removed by rereading.
