    摘要: A method and apparatus for an address generation circuit. In one embodiment, the method includes computing a carry-in for at least one group of a predetermined number of bits of a propagate and a generate signal formed from a plurality of logical address components. Once the carry-in is computed, a plurality of conditional sums are generated for a logic 0 carry-in and a logic 1 carry-in. Subsequently, a sum is selected from the plurality of conditional sums to form a first portion of an effective address from the logical address components in a first stage and a second portion of the effective address in a second stage. In one embodiment, a fully dynamic high-performance sparse tree adder circuit that generates one in four carries, is used to form an address generation circuit, in accordance with one embodiment. Other embodiments are described and claimed.

    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.
