Abstract
Disclosed is a semiconductor memory device having the least pin counts per chip to test the maximum number of chips in a single wafer at a time. The semiconductor memory device includes an address counter generating a plurality of address signals in response to a signal provided from the outside, an address selection circuit controlling a path of the address signals, a plurality of switches divided in a predetermined number of switch groups and connected between a memory array and data input/output pins, and a switch control circuit generating switch control signals to control a switching operation of the switch groups. A portion of the data input/output pins is employed in correspondence with the number of the switch groups.
