Abstract

PURPOSE:To prevent an overcurrent from being inputted to a receiver element by sending only signals, selected in refresh mode by making a bus connection between the transmitter circuit of a memory unit and the receiver circuit of CPV. CONSTITUTION:Request acceptance signals (a1), (a2)... of transmitter circuits 31, 32... corresponding to a memory unit receiving refresh request become high-level binary signals by passing through a register, etc., and transmission information assignment signals (b1), (b2)... become effective through AMD gates 31c, 32c... and OR gates 31d, 32d.... Then, only constant-current driving elements 31a, 32a... of circuits 31, 32... with high-level outputs of AND gates 31b, 32b... are driven to sent simultaneously only signals selected on signal lines 20 and 21 connecting receiver circuit 10 of CPV to circuits 31, 32.... Therefore, differential signal receiver elements 10a, 10b... of circuit 10 are never applied at the same time with acceptance request signals from all memory elements at the tme of refresh operation, so that an acceptance failure, damage, etc., due to an input overcurrent will not occur.
