摘要： Testing of a multibank memory device having a plurality of memory banks which includes activating two or more of the plurality of memory banks for participation in the test; selecting at least one common memory address corresponding to a memory cell within each activated bank; simultaneously writing test data into the selected memory cell of each activated bank;
simultaneously reading the test data previously written into the selected memory cell of each activated bank; and comparing the test data read from each activated bank with the test data from each other activated bank and if a match is determined to exist, then indicating a pass condition, else indicating a fail condition.
