Semiconductor memory device having advanced test mode

摘要

An apparatus for testing an operation of a semiconductor memory device having a plurality of banks in a compress test mode includes an internal address generator for receiving an external bank address and generating internal bank addresses in response to a bank interleaving test signal; a read operation testing block for receiving the internal bank addresses and testing a read operation of the semiconductor memory device in response to the bank interleaving test signal; and a write operation testing block for receiving the internal bank addresses and-testing a write operation of the semiconductor memory device.
