Adjustable voltage drop detection threshold in a memory device

Abstract:

Devices and techniques for an adjustable voltage drop detection threshold in a memory device are disclosed herein. A voltage drop detection threshold of a memory device is dynamically established. A power loss event is triggered when the supply voltage falls below the voltage drop detection threshold. An error parameter associated with performing multiple memory operations on the memory device is collected. The multiple memory operations are performed while applying a supply voltage at a second supply voltage level of the memory device which is less than a first supply voltage level established as a first operating voltage for the memory device. Determining whether the error parameter is below an allowable error threshold. In response to determining that the error parameter is below the allowable error threshold, the voltage drop detection threshold is established at a voltage level less than the first supply voltage level.
