摘要： A semiconductor memory device is of a bank switching type having a plurality of memory array banks provided in a memory chip which can be switched from one to another for storage operation. The semiconductor memory device includes: a plurality of memory arrays in the memory array banks; an input/output circuit for transmitting information data between the memory arrays and the outside; a data bus for connecting between the memory arrays and the input/output circuit; and N-channel transistors provided across the data bus. The data bus consists of a plurality of adjacent lines. Each of N-channel transistors is connected at their drain to the corresponding lines of the data bus while at their source to the ground. When a multi-bit test is commenced for writing and reading data on the memory arrays, the N-channel transistors are turned on to connect the lines of the data bus to the ground.
