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.

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: Embodiments extend the capability of fuse elements, anti-fuse elements, and combinations thereof to enable multi-time programmable memory elements. Accordingly, embodiments significantly reduce area requirements and control circuitry complexity of memory elements. Embodiments can be used in non-volatile memory storage, for example, and are suitable for use in system on chip (SoC) products.

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.
