  • Patent number: 11483167
    Abstract: Physically unclonable functions response in memory cells is improved by transistor sizing, transistor threshold voltage (VT) and body bias in the memory cell to improve the reproducibility of the memory cell and multiple Sense Amplifiers (SA) per column to further enhance physically unclonable function entropy. A physically unclonable function exploits a large number of read-sequence-order combinations available in a physically unclonable function memory array to generate an exponentially large challenge-response pair space, without incurring the area and energy costs of hosting and operating an exponentially large memory array.

  • Patent number: 9401199
    Abstract: A storage cell is provided with improved robustness to soft errors. The storage cell comprises complementary core storage nodes and complementary outer storage nodes. The outer storage nodes act to limit feedback between the core storage nodes and are capable of restoring the logical state of the core storage nodes in the event of a soft error. Similarly the core storage nodes act to limit feedback between the outer storage nodes with the same effect. This cell has advantages compared with other robust storage cells in that there are only two paths between the supply voltage and ground which limits the leakage power. An SRAM cell utilizing the proposed storage cell can be realized with two access transistors configured to selectively couple complementary storage nodes to a corresponding bitline. A flip-flop can be realized with a variety of transfer gates which selectively couple data into the proposed storage cell.

  • Patent number: 8536898
    Abstract: A sense amplifier for use in a memory array having a plurality of memory cells is provided. The sense amplifier provides low power dissipation, rapid sensing and high yield sensing operation. The inputs to the sense amplifier are the differential bitlines of an SRAM column, which are coupled to the sense amplifier via the sources of two PMOS transistors. A CMOS latching element comprised of two NMOS transistors and the aforementioned PMOS transistors act to amplify any difference between the differential bitline voltages and resolve the output nodes of the sense amplifier to a full swing value. The latching element is gated with two additional PMOS transistors which act to block the latching operation until the sense amplifier is enabled. One or more equalization transistors ensure the latch remains in the metastable state until it is enabled. Once the latch has resolved it consumes no DC power, aside from leakage.

  • Patent number: 8488403
    Abstract: An offset cancellation scheme for sense amplification is described. The scheme consists of group of transistors which are selectively coupled to high and low voltage levels via multi-phase timing. This results in a voltage level on sensing nodes of interest which are a function of transistor mismatch. The resulting voltage levels act to compensates for the transistor mismatch, thereby improving the reliability of the sense amplifier in the presence of process non-idealities. The offset cancellation scheme is applicable to numerous types of sense amplifiers, amplifiers, and comparators.
