Abstract
A cell in a multiport memory is connected to a respective bit line via respective switches. A write enable element is located between the switches and an input of the cell's storage device. A read enable element is located between an output of the storage device and the same switches. Thus, read bit lines and write bit lines are merged and the number of switches per cell is drastically reduced with respect to prior art multiport memories.
