Abstract
A semiconductor memory circuit comprises a memory array including an X decoder and column units. Each of the column units has a Y decoder, memory cells and bit line pairs. The semiconductor memory circuit further comprises switching circuits each having an input connected to one of the Y decoders and outputs. The switching circuit is connected to the input and one of the outputs in response to a control signal. The semiconductor memory circuit further comprises buffers each of which is connected to one of the outputs of the switching circuits, ports each of which is connected to one of the buffers and a memory control signal generating circuit outputting the X address and Y address.
