Abstract:
1. A storing apparatus, comprising: a communication unit configured to communicate with an external device; a register arranged to store information temporarily; a memory configured to have a plurality of blocks including substitute blocks for defective blocks and to store threshold value information, which is used for warning lowering of a remaining amount of the substitute blocks in the memory, indicating a predetermined value; a control unit configured to control writing data into the memory, wherein the control unit reads out the threshold value information from the memory and stores the read-out threshold value information into the register, wherein the control unit updates, in accordance with an update instruction from the external device received by the communication unit, the threshold value information read-out from the memory and stored in the resister with threshold value information received from the external device, wherein the control unit compares a threshold value indicated by the updated threshold value information stored in the resister and a remaining amount of the substitute blocks in the memory and transmits a predetermined notice to the external device by the communication unit in accordance with the remaining amount of the substitute blocks being equal to or less than the threshold value indicated by the updated threshold value information stored in the register, and wherein the updated threshold value is inhibited from being copied from the resister to the memory by the control unit.
