Memory device and computing system including the same

摘要

A memory system includes a read-only memory (ROM), a main memory and a processor. The ROM stores a basic input/output system (BIOS). The main memory includes a fail address table which stores at least one fail address designating a memory cell row having at least one defective cell. The processor receives fail information of the at least one fail address from the main memory and loads data associated with a booting operation of the memory system in a safe area of the main memory by avoiding a fail area corresponding to the at least one fail address during power-on operation while a power is applied to the memory system. The data associated with the booting operation is stored in a storage device.

1. A memory device, comprising:
a read-only memory (ROM) configured to store a basic input/output system (BIOS) therein; a main memory configured to store a fail address table therein, the fail address table configured to store at least one fail address therein, the fail address designating a memory cell row having at least one defective cell; and a processor coupled to the ROM and the main memory, the processor configured to,
receive fail information of the at least one fail address from the fail address table, andload, from a storage device, data associated with a booting operation of the memory device into a safe area of the main memory by,
loading the BIOS from the ROM to the safe area of the main memory based on the fail information such that the processor avoids loading the data in a fail area of the main memory corresponding to the at least one fail address,executing the loaded BIOS, andperforming a power-on self-test (POST) on the memory device and the storage device using the BIOS.
