摘要： Techniques and circuitry are disclosed for efficiently implementing programmable memory array circuit architectures, such as PROM, OTPROM, and other such programmable non-volatile memories. The circuitry employs an antifuse scheme that includes an array of memory bitcells, each containing a program device and an antifuse element configured with current path isolation well and for storing the memory cell state. The bitcell configuration, which can be used in conjunction with column/row select circuitry, power selector circuitry, and/or readout circuitry, allows for high-density memory array circuit designs and layouts.

摘要： An array of memory cells is disclosed. The memory cell includes a fuse and at least one transistor. The transistor is used to control the programming or sensing of the fuse. A program voltage is applied to a stack of first and second conductive layers. A first portion of the stack couples the program voltage to a terminal of the transistor in a cell. A second portion of the stack couples the program voltage to a terminal of the transistor in another cell.
