Abstract
A device includes a memory array and a sense amplifier (SA) coupled with the memory array and with an input/output (I/O) data line. The SA is to receive bits of data over the I/O data line in association with a program operation. A digital-to-analog converter (DAC) is coupled with the SA, the DAC to convert the bits of data to an analog voltage value. An analog memory element is coupled with the DAC, the analog memory element to store the analog voltage value for a period of time until the bits of data are programmed to the memory array.

A device comprising:
- a memory array;
- a sense amplifier (SA) coupled with the memory array and with an input/output (I/O) data line, wherein the SA is to receive bits of data over the I/O data line in association with a program operation;
- a digital-to-analog converter (DAC) coupled with the SA, the DAC to convert the bits of data to an analog voltage value;
- and
- an analog memory element coupled with the DAC, the analog memory element to store the analog voltage value for a period of time;
- and
- an analog-to-digital converter (ADC) coupled between the analog memory element and the SA, wherein the ADC is to, after the period of time, convert the analog voltage value to the bits of data, and wherein the SA is to program the bits of data to the memory array.

A device comprising:
- a memory array;
- a sense amplifier (SA) coupled with the memory array and with an input/output (I/O) data line, wherein the SA is to retrieve bits of data from the memory array in response to a read operation;
- a digital-to-analog converter (DAC) coupled with the SA, the DAC to convert the bits of data to an analog voltage value;
- and
- an analog memory element coupled with the DAC, the analog memory element to store the analog voltage value for a period of time until the bits of data are transmitted out to the I/O data line.
