Abstract
A non-volatile, low, and zero power, high speed self-sensing programmable device and architecture including a non-volatile self-sensing cell. The non-volatile self-sensing cell is connected out of the speed path of the programmable device, permitting rapid, non-volatile programming and reading operations to be conducted. According to one version, two self-sensing cells are provided with a means for selecting one of the cells for programming or read operation. Each non-volatile self-sensing cell includes a latch having cross-coupled, pull-up transistors and non-volatile pull-down cells. The cross-coupled pull-up transistors are field effect transistors having gates which are connected to the opposite sources of the cross-coupled pull-up transistors.
