Read voltage calibration for copyback operation

A system, comprising:

• a memory device;
• and
• a processing device communicatively coupled to the memory device and configured to:
• determine, in response to a trigger event, a calibrated read voltage value associated with a first portion of a first group of memory cells of the memory device, wherein the first portion is configured to store time based telemetric sensor data to be copied to a second group of memory cells of the memory device;
• and
• in response to a bit error rate (BER) of a second portion of the first group of memory cells determined using the calibrated read voltage value being below a threshold BER, perform a copyback operation on the first group to copy the time based telemetric sensor data to the second group
• wherein the system further comprises a plurality of sensors, and wherein the time based telemetric sensor data are obtained from different sensors of the plurality and aggregated prior being received at the processing device.

A method, comprising:

• prior to copying data from a first location of a memory device to a second location of the memory device via a copyback operation:
• determining a calibrated read voltage by performing a read voltage calibration on a first sample portion of the first location;
• and
• determining a bit error rate (BER) of a second sample portion of the first location using the calibrated read voltage;
• and
• responsive to the determined BER of the sample portion of the second location being above a threshold BER:
• performing a read voltage calibration on the second sample portion of the first location;
• and
• performing, subsequent to the read voltage calibration, the copyback operation on the first location to copy the data from the first location to the second location.
