Abstract
Disclosed is a method of controlling an MRS operation in a memory device which can prevent an unnecessary MRS operation due to a malfunction of the memory device at a time when the memory device exits from a self-refresh mode. According to this method, external addresses are used to intercept a mode register set command signal that enables the MRS operation at a time point at which the memory device exits from the self-refresh mode.
Claims10
A method of controlling a mode register set (MRS) operation in a memory device when the memory device exits from a self-refresh mode, the method comprising the step of intercepting a mode register set command signal that enables the MRS operation using an external address after recognizing a time point at which the memory device exits from the self-refresh mode.
A circuit of controlling a mode register set (MRS) operation in a memory device that receives an MRS-related control signal and outputting a mode register set command signal for enabling the MRS operation, the circuit comprising an intercepting unit for receiving an external address and intercepting the mode register set command signal.
