Patent ID: 8917562

Claim:
A body voltage based sense circuit (BVSC) apparatus for short pulse reading (SPR) of a memory, said apparatus comprising: a body voltage sensing data circuit configured to sense resistance of a memory cell that has two states, said body voltage sensing data circuit having a voltage output in response to short pulse reading (SPR) of said memory cell; said body voltage sensing data circuit configured to translate the states of the memory cell into a sense data voltage signal; a body voltage sensing reference circuit configured to generate a sense reference voltage signal; a second stage sense amplifier configured to compare said sense data voltage signal and said sense reference voltage signal and output a data signal; and a capturing latch circuit configured to capture said data signal using positive feedback; wherein said captured data signal digitally represents the state of said memory cell as a binary output; and wherein said body voltage sensing is performed on a body-connected load that provides a high sensing margin (SM) in which body and drain terminals of a transistor of said body voltage sensing data circuit are coupled together.
