Selective overdrive of supply voltage to primary switch for programming memory cells
Abstract:
A circuit includes a linear regulator operatively coupled with a memory array, the linear regulator including a primary switch to generate a regulated voltage usable to program memory cells of the memory array. A first digital-to-analog converter (DAC) includes an output coupled with the linear regulator. A pump regulator is operatively coupled with a charge pump, where the charge pump is to provide a supply voltage to the linear regulator. A second DAC includes an output coupled with the pump regulator. Control logic, operatively coupled with the first DAC and the second DAC, is to perform operations including: causing a first digital input value to be provided to the first DAC to selectively smooth noise on the supply voltage; and causing a second digital input value to be provided the second DAC to selectively adjust the supply voltage based on a programmable offset value.
