SEMICONDUCTOR MEMORY DEVICE HAVING CURRENT ADDRESS COUNTER

PURPOSE: A semiconductor memory device having a current address counter is provided to reduce the write test procedure and time by enabling to check write operation only with an input of continuous data after designating a first address. CONSTITUTION: In a module device of a DRAM having an EEPROM, a semiconductor memory device having a current address counter(20) performs the write operation of the whole chip by a continuous address signal being output through the current address counter. The current address counter(20) generates a series of continuous address signals by performing the counting with n bits in response to an input address signal during the current address write operation. Therefore, the device enables the sequential write only with data, without inputting the address by a clock synchronization, and therefore the number of clocks and the whole write time can be reduced. The circuit comprises a normal address counter(10) outputting a signal whose address is increased by +1 by m bit counting the input address signal and the current address counter(20).
