摘要
An integrated circuit includes a memory cell that stores a data bit corresponding to one of a low and a high voltage. A memory element is coupled to a data node for storing the data bit and to an inverse data node for storing an inverse of the data bit. At least one write-access port has a write-access switch having an input terminal coupled to a data input line, an output terminal coupled to the data node, and a control terminal coupled to a write control line for switching the write-access switch on or off to provide a write-data bit from the data input line to the write-access port. A preset switch is employed which has a first terminal coupled to one of the data node and the inverse data node, a second terminal coupled to a voltage source sufficient to cause the data node to store a logic-1 data bit when the preset switch is on, and a preset control terminal for switching the preset switch on or off to preset the memory cell before a write operation is coupled to a preset control line.
