Memory And Accessing Method Thereof

A memory device, comprising:

• an address encoding selector for selecting one of plurality of encoding circuits which encodes a first address into a second address, the encoding circuits having N types of encoding functions;
• a data decoding selector for selecting one of plurality of decoding circuits which decodes a first data corresponding to the second address into a second data, the decoding circuits having M types of decoding functions;
• and
• a non-volatile memory, coupled to the address encoding selector and the data decoding selector, for storing the first data;
• wherein the non-volatile memory being a read-only memory (ROM).

A method for accessing a memory device, comprising:

• encoding a first address into a second address by an address encoding selector;
• and
• decoding a first data corresponding to the second address into a second data by a data decoding selector;
• wherein the first data being stored in a non-volatile memory.
