Apparatus and method and computer program product for handling flash physical-resource sets

A method for handling flash physical-resource sets, performed by a processing unit when loading and executing program code of a flash translation layer, comprising:

• during a performance of an operation, after writing a number corresponding to a physical-resource set into a set-selection register of an address conversion circuit, sending a memory address for a variable value to be read or written into the address conversion circuit, thereby enabling the address conversion circuit to convert the memory address into a relative address corresponding to allocated space for the physical-resource set and output the relative address to a random access memory (RAM);
• and reading the variable value from the relative address of the RAM, or writing the variable value into the relative address of the RAM.

A non-transitory computer program product for handling flash physical-resource sets when executed by a processing unit, the non-transitory computer program product comprising program code of a flash translation layer (FTL) to:

• during a performance of an operation, after writing a number corresponding to a physical-resource set into a set-selection register of an address conversion circuit, send a memory address for a variable value to be read or written into the address conversion circuit, thereby enabling the address conversion circuit to convert the memory address into a relative address corresponding to allocated space for the physical-resource set and output the relative address to a random access memory (RAM);
• and read the variable value from the relative address of the RAM, or writing the variable value into the relative address of the RAM.
