摘要:
A localized direct sense architecture circuit includes a large number (e.g. 8) of microcells, each having a primary sense amp PSA, coupled to one global data line which is coupled to one secondary sense amp SSA. Each PSA includes its own bias current device, which supplies bias current to sense devices in the PSA and is also used for precharge, such that the bias current does not flow along the highly capacitive global data line. With this technical approach, the size of each bias current supply device can be substantially reduced, and the number of PSAs on one global data line can be increased for increased layout density.
