Abstract: Various embodiments of the present disclosure relate to a memory management method and apparatus which perform a memory return operation by dynamically setting a memory threshold value by additionally considering performance information of an electronic apparatus in addition to an amount of available memory. An electronic apparatus comprises: a memory that stores at least one instruction corresponding to at least one program; and at least one processor, comprising processing circuitry, electrically connected to the memory, wherein at least one processor, individually and/or collectively, is configured to execute the at least one instruction as a process, and to: acquire performance information of the electronic apparatus and an amount of available memory; determine a memory threshold value based on the performance information and the amount of available memory; update a memory threshold value to the determined memory threshold value; and based on the amount of available memory being less than the memory threshold value at a certain point in time, terminate a certain process.

Abstract: A memory operation device and method for operating a memory in an electronic device. The electronic device may determine whether a memory leak occurs in one or more low-order stack trace items with a count value of n among collected stack trace items, n being a positive integer, and, based on a low-order stack trace item among the collected stack trace items being determined as causing a memory leak, proceeding to a next order of the collected stack trace items to thereby determine whether a memory leak occurs in one or more high-order stack trace items with a count value of m which is a positive integer higher than n). When m is a maximum count value among the collected stack trace items, memory debugging may be performed using a high-order stack trace item, among the one or more high-order stack trace items, causing the memory leak.

Abstract: A switching mode power supply including: a power input unit configured to receive an input alternating current (AC) voltage; a rectification unit configured to rectify the input AC voltage; a condenser configured to smooth the rectified input AC voltage; a current detection unit configured to detect a surge current flowing in the condenser; and a converter including switching elements, the converter being outputting a direct current (DC) voltage based on a voltage applied to first and second ends of the condenser and on/off duty ratios of the switching elements. The switching elements are configured to be turned off based on the surge current being detected by the current detection unit.
