  • Patent number: 8164942
    Abstract: Embedded dynamic random access memory (eDRAM) sense amplifier circuitry in which a bit line connected to each of a first plurality of eDRAM cells is controlled by cell control lines tied to each of the cells. During a READ operation the eDRAM cell releases its charge indicating its digital state. The digital charge propagates through the eDRAM sense amplifier circuitry to a mid-rail amplifier inverter circuit which amplifies the charge and provides it to a latch circuit. The latch circuit, in turn, inverts the charge to correctly represent at its output the logical value stored in the eDRAM cell being read, and returns the charge through the eDRAM sense amplifier circuitry to replenish the eDRAM cell.
