    摘要: Decoder circuits capable of decoding encoded ROM memory are provided. Embodiments provide several improvements over prior solutions which rely primarily on CMOS logic (e.g., inverters). For example, embodiments provide faster decoding by limiting the number of decoding stages to a single stage. Further, embodiments allow the use of partial swing (as opposed to full swing) on the bit lines, which results in significant power reduction. This, in turn, results in reduced amounts of capacitor discharges when reading the data.

    摘要: A quad SRAM based one time programmable memory cell is provided. Prior to programming, the memory cell operates as an SRAM memory cell. After programming, the memory cell operates as a one-time programmable non-volatile memory cell. The memory cell includes a storage element coupled at a first side to a first upper fuse and a first lower fuse and coupled at a second side to a second upper fuse and a second lower fuse. When the first upper fuse and second lower fuse are programmed, the storage element outputs a first value. When the second upper fuse and first lower fuse are programmed, the storage element outputs a second value. After programming the upper fuse acts as a pull-up fuse and the lower fuse acts as a pull-down fuse hold the state of the cell.

    摘要: A one-time programmable device includes a controller, a protection system, a static storage element and a latch, which can be referred to as a latch-based one-time programmable (OTP) element. In one example, the static storage element includes a thin gate-oxide that acts as a resistance element, which, depending on whether its blown, sets the latch into one of two states.

    摘要: The present invention relates to a one-time programmable memory cell and a method of setting a state for a one-time programmable memory cell. The memory cell includes a storage element adapted to store data and two thin gated fuses coupled to the storage element, adapted to set the state of the memory cell. A level shifter device is connected to the gated fuses and is adapted to stand off a high voltage when setting the state of the memory cell. At least one switch transistor is connected to at least the level shifter device and is adapted to select at least one of the gated fuses, enabling a high voltage to be communicated thereto, thus setting the state of the memory cell. A programming device is coupled to the storage element and is adapted to keep at least one of the gated fuses low when setting the state of the memory cell.

    摘要: According to an exemplary embodiment, a memory array arrangement includes a plurality of word lines, where at least two of the plurality of word lines are concurrently active word lines. Each of the plurality of word lines drive at least one group of columns. The memory array arrangement also includes a multiplexer for coupling one memory cell in a selected group of columns to at least one of the plurality of sense amps, thereby achieving a reduced sense amp-to-column ratio. The memory array arrangement further includes a plurality of I/O buffers each corresponding to the at least one of the plurality of sense amps. The memory array arrangement thereby results in the plurality of word lines having reduced resistive and capacitive loading.

    摘要: A differential latch-based one time programmable memory cell is provided. The differential latch-based one time programmable memory cell includes a differential latching amplifier having a first set of fuse devices coupled to the first input and a second set of fuse devices coupled to the second input. Only one set of fuse devices can be programmed in a memory cell. If one or more fuse devices in a set of fuse devices are programmed, the side having the programmed fuse will present a lower voltage at its input to the differential latching amplifier. Differential latching amplifier outputs a “0” or a “1” depending on the side having the programmed fuse.
