Abstract
A circuit has a storing portion, a write portion and a read portion. In one embodiment, read portion has a transistor which has a substantially thinner gate oxide than the transistors in the storing portion and the transistors in the write portion. In an alternate embodiment, circuit has a plurality of read ports. In an alternate embodiment, selecting the optimal gate oxide thickness for the transistors in circuit allows the trade-off between transistor switching speed and gate leakage current to be optimized to produce a circuit having a fast enough read access time and a low enough standby power.
