ABSTRACT:
Provided are an apparatus and method of transmitting working context, which can minimize power consumption in a power-off standby mode of a portable apparatus including a system on a chip, where the method includes selecting a power-off standby mode, transmitting working context with respect to a hardware module, which is mounted on a semiconductor chip, to a predetermined memory, and storing the working context in the predetermined memory, transmitting the working context stored in the memory to a non-volatile memory outside the semiconductor chip, and storing the working context in the non-volatile memory, and executing the power-off standby mode; where the method may further include releasing the power-off standby mode, restoring the working context with respect to the hardware module, which is stored in the non-volatile memory, to the predetermined memory, and recovering the at least one hardware module to a state existing immediately before the power-off standby mode was executed by using the working context restored to the memory from the non-volatile memory.
