    • A differential fuse sensing system includes a fuse leg configured for introducing a sense current through an electrically programmable fuse (eFUSE) to be sensed, and a differential sense amplifier having a first input node coupled to the fuse leg and a second node coupled to a reference voltage. The fuse leg further includes a current supply device controlled by a variable reference current generator configured to generate an output signal therefrom such that the voltage on the first input node of the sense amplifier is equal to the voltage on the second input node of the sense amplifier whenever the resistance value of the eFUSE is equal to the resistance value of a programmable variable resistance device included within the variable reference current generator.

    • A compiler for building at least one compilable SRAM including at least one compilable sub-block. A global control clock generation circuit generates a global control signal. At least one local control logic and speed control circuit controls the at least one compilable sub-block. The local control logic and speed control circuit is controlled by the global control signal. An algorithm receives an input capacity and configuration for the sub-block of the SRAM array. An algorithm determines a number of wordlines and bitlines required to create the sub-block of the input capacity. An algorithm optimizes a cycle time of the sub-block by determining global control clock circuits based upon the number of wordlines and bitlines in the sub-block. An algorithm optimizes access time of the sub-block by determining local speed control circuits based upon the number of wordlines and bitlines.
