Assignee: MICRON TECHNOLOGY, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A memory device comprising:
an array of memory cells;
a diode having a threshold voltage that changes with temperature;
an analog-to-digital converter (ADC) coupled with the array and comprising:
a voltage comparator having a positive terminal coupled with the diode;
a first capacitor coupled between a negative terminal of the voltage comparator and ground; and
a second capacitor selectively coupled between the first capacitor and a voltage reference node, the second capacitor also coupled with the ground and having a smaller capacitance than that of the first capacitor; and

a pulse generator coupled with the ADC and to generate pulses, wherein the pulses are to cause the first capacitor to connect to the second capacitor and equalize charge between the first capacitor and the second capacitor, and wherein an inverted signal of the pulses is to cause the second capacitor to be coupled with the voltage reference node to pre-charge the first capacitor.
