ABSTRACT:
Methods and apparatus are provided for read/write control and bit selection with false read suppression in an SRAM. According to one aspect of the invention, a bit select circuit is provided for an SRAM. The disclosed bit select circuit includes one or more transistors controlled by a write control gate signal to prevent data from being read from one or more data cells during a write operation. The transistors can include, for example, a pair of gated transistors controlled by the write control gate signal. The write control gate signal prevents data from being read from one or more data cells while the write control gate signal is in a predefined state.
