Patent ID: 11892862
Assignee: MICRON TECHNOLOGY, INC.
Field: Control (Instruments)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An apparatus comprising:
a first reference voltage generator configured to generate a first voltage;
a second reference voltage generator configured to generate a second voltage;
a detection circuit configured to compare the first voltage with the second voltage to generate a selection signal; and
a selection circuit configured to select one of the first and second voltages responsive to the selection signal,
wherein the detection circuit is configured to have a hysteresis property in changing a state of the selection signal,
wherein the detection circuit includes a current mirror circuit having an input current path flowing an input current controlled by one of the first and second voltages and an output current path flowing an output current controlled by other of the first and second voltages,
wherein the current mirror circuit further includes a first additional current path coupled in parallel with one of the input current path and the output current path, and
wherein the first additional current path is configured to be enabled responsive to the selection signal.
