Title: Semiconductor storage device
Inventor: YAMANOI GORO
IPC: G11C11/41
Filed: 1991-10-24
Abstract: PURPOSE:To reduce the size of a transistor TR for initialization and to stably initialize storage elements by successively initializing storage elements with each word line as the unit. CONSTITUTION:When a signal is inputted from one of monitor bit output signal lines 15a to 15e, a one shot pulse generating circuit 15 outputs a pulse signal to a NOR circuit 18 through signal lines 17a to 17e. The circuit 18 outputs a signal to an address counter 20 through a signal line 19 to increment the value of a counter 20. When initialization of elements 1a to 1e is detected, the counter 20 generates an address for the next word line out of word lines 4a to 4e connected to initialized elements and inputs the address signal to an address decoder 5 through an address switching circuit 21. This constitution reduces the driving capability of a switch for initialization and reduces its size. Further, a supply voltage is less changed to stabilize the operation.
