The present disclosure provides apparatuses and methods for operating a flash memory for programming operating system (OS) data before an surface mount technology (SMT) process. In some embodiments, the method includes erasing a plurality of memory cells in a memory block, reducing a lateral charge loss of the plurality of memory cells due to high temperature degradation during the SMT process by applying a pre-program voltage to word lines coupled to the memory block, and performing multi-bit programming of the OS data in the plurality of memory cells, prior to performing the SMT process. The applying of the pre-program voltage causes threshold voltages of the plurality of memory cells to increase.

Flash memory for reducing reliability degradation of OS data due to SMT process

A clothes care apparatus including a main body having a care compartment with an exhaust port and a supply port; a heat exchanger in the main body; a blowing fan in the main body to generate airflow supplied to the care compartment through the supply port; an exhaust flow path to guide airflow from the exhaust port to pass through the heat exchanger; a circulation flow path to guide airflow from the exhaust flow path to the fan; a bypass opening to connect the care compartment and the circulation flow path; and a bypass door to open and close the bypass opening. When the bypass opening is open, at least a portion of the airflow flows directly into the circulation flow path without passing through the exhaust flow path. When the bypass opening is closed, none of the airflow flows directly from the care compartment into the circulation flow path.
