Abstract:
1. A memory storage apparatus, comprising: a rewritable non-volatile memory module, having a plurality of physical blocks; a first circuit, outputting a state signal, wherein when the first circuit is enabled, the first circuit keeps the state signal in a first state and after a predetermined condition is satisfied, the first circuit transfers the state signal from the first state to a second state and keeps the state signal in the second state; a memory controller, coupled to the first circuit and the rewritable non-volatile memory module and configured to receive the state signal from the first circuit; and a power management circuit, coupled to the first circuit and the memory controller and configured to receive an input voltage and supply an output voltage to the rewritable non-volatile memory module and the memory controller after the memory storage apparatus is powered on, wherein the memory controller is further configured to output a second signal when the memory controller receives a first signal from a host system, and the power management circuit is further configured to stop outputting the output voltage when the memory controller outputs the second signal, and wherein the memory controller is further configured to determine whether the state signal is in the first state when the memory controller is enabled, and if the state signal is in the first state, the memory controller performs a first procedure, and if the state signal is not in the first state, the memory controller performs a second procedure.
