Memory management circuit, electronic device and memory management method

An electronic device, comprising:

• a computing circuit, configured to perform a computing operation;
• a memory device, configured to provide available storage spaces for the computing circuit during the computing operation;
• and
• a memory management circuit, coupled to the computing circuit and the memory device, comprising:
• a controller, configured to record first addresses of the available storage spaces within the memory device, and control operations of generating a mapping table in response to a storage request of the computing circuit, wherein the controller comprises:
• a searching logic, configured to store the first addresses in a storage device and generate the mapping table, wherein the first addresses are queued with a specific order in the storage device;
• wherein when the computing circuit sends the storage request to request for a specific capacity of storage, the searching logic obtains at least one first address of the first addresses queued in the storage device according to the specific order of the first addresses queued in the storage device, to generate the mapping table according to the at least one first address obtained from the storage device;
• and
• an address mapping logic, coupled to the controller, configured to perform an address mapping operation upon the storage request according to the mapping table, to allow the computing circuit to utilize at least a portion of the available storage spaces within the memory device according to the mapping table.

A memory management method, applicable to a memory management circuit, comprising:

• utilizing a controller of the memory management circuit to record first addresses of available storage spaces within a first memory device;
• utilizing a searching logic of the controller to store the first addresses in a storage device, wherein the first addresses are queued with a specific order in the storage device;
• in response to a computing circuit sending a storage request to request for a specific capacity of storage, utilizing the searching logic to obtain at least one first address of the first addresses queued in the storage device according to the specific order of the first addresses queued in the storage device, to generate a mapping table according to the at least one first address obtained from the storage device;
• and
• utilizing an address mapping logic of the memory management circuit to perform an address mapping operation upon the storage request according to the mapping table, to allow the computing circuit to utilize at least a portion of the available storage spaces within the first memory device according to the mapping table.
