Memory device for performing temperature compensation and operating method thereof

Abstract

A memory device for performing temperature compensation and an operating method thereof are provided. The memory device includes a memory cell array; a page buffer circuit connected to the memory cell array through a plurality of bit lines, including a page buffer connected to each of the plurality of bit lines, and configured to perform a pre-charge operation during a pre-charge period for data reading; and a control logic configured to differently control the pre-charge operation of the page buffer circuit according to a detected temperature, wherein the pre-charge period includes a first period in which the plurality of bit lines are overdriven and a second period in which the plurality of bit lines are driven at a voltage lower than that of the first period, and the first period where the detected temperature is a first temperature is set to be shorter than the second period where the detected temperature is a second temperature higher than the first temperature.
