Abstract:
A semiconductor memory includes a bit cell having first and inverters forming a latch. First and second transistors are respectively coupled to first and second storage nodes of the latch and to first and second write bit lines. Each of the first and second transistors has a respective gate coupled to a first node. Third and fourth transistors are coupled together in series at the first node and are disposed between a write word line and a first voltage source. Each of the first and second transistors has a respective gate coupled to a first control line. A fifth transistor has a source coupled to a second voltage source, a drain coupled to at least one of the inverters of the latch, and a gate coupled to the first node. A read port is coupled to a first read bit line and to the second storage node of the latch.
