Abstract: An electronic device is provided. The electronic device includes a storage, a volatile memory, and a processor, wherein the processor is configured to identify temperature information based on a temperature of the volatile memory and a temperature of the processor, to identify a first temperature section corresponding to the temperature information among a plurality of predetermined temperature sections, to perform calibration of the volatile memory to acquire an operation parameter corresponding to the first temperature section, and to adjust a timing between signals for controlling an operation of the volatile memory based on the operation parameter.

Abstract: An electronic device includes a power management circuit; a volatile memory; and a processor configured to: based on the electronic device starting system booting, identify whether the system booting is initial booting or whether a condition designated in the volatile memory is satisfied, based on identifying that the system booting is the initial booting or the condition is satisfied, identify a lower positive supply voltage (LVDD) value for the volatile memory by testing an LVDD margin for the volatile memory, and based on the LVDD value being less than a reference LVDD value for the volatile memory, drive the volatile memory using the LVDD value.
