Abstract
A semiconductor memory device includes a memory cell array including a plurality of memory banks, an address input portion which receives a row address and a column address through address pins during a normal mode operation and which receives the row address, the column address and write data through the address pins during a test mode operation, an address decoder which accesses one of the plurality of memory banks during the normal mode operation and at least two of the plurality of memory banks during the test mode operation in response to the row address and the column address, a data input portion which inputs write data applied through data pins to the memory cell array during the normal mode operation and which inputs write data output from the address input portion to the memory cell array during the test mode operation, and a data output portion which outputs read data output from the memory cell array to the data pins during the normal mode operation and the test mode operation.
