发明名称 Subtraction circuits and digital-to-analog converters for semiconductor devices
摘要 A memory device that, in certain embodiments, includes a plurality of memory elements connected to a bit-line and a delta-sigma modulator with a digital output and an analog input, which may be connected to the bit-line. In some embodiments, the delta-sigma modulator includes an adder with first and second inputs and an output. The first input may be connected to the analog input. The delta-sigma modulator may also include an integrator connected to the output of the adder, an analog-to-digital converter with an input connected to an output of the integrator and an output connected to the digital output, and a digital-to-analog converter with an input connected to the output of the analog-to-digital converter and an output connected to the second input of the adder.
