Abstract:
Integrated circuits that include SRAM cells having additional read stacks are provided. In accordance with one embodiment an integrated circuit includes a memory storage array of memory cells. The integrated circuit includes a read stack coupled to each memory cell of the memory storage array. Each read stack includes a read pull-down transistor having a first threshold voltage, and a read pass gate transistor coupled in series with the read pull down transistor and having a second threshold voltage greater than the first threshold voltage.
