Removable Mother/Daughter Peripheral Card

A non-volatile memory device assembly, comprising:

• a memory card comprising:
• a first connector;
• a flash array;
• encoded user data stored in a first portion of the array;
• and
• information useful to decode the encoded user data stored in a second portion of the array;
• and
• a mother card comprising:
• a second connector, whereby the mother card is removably connectable to the memory card by connecting of the first and second connectors to one another;
• a third connector whereby the mother card can be removably coupled to a host, wherein the third memory connector uses a different pin connector structure from the first connectors pin connector structure;
• and
• a module having a controller function that decodes the encoded user data using said information when the mother card is removably coupled to the host and the memory card is removably connectable to the mother card, the user data being transferrable from the memory card to the host via the mother card,
• wherein the information useful to decode the stored encoded user data includes a decoding algorithm used by the module to decode the encoded user data,
• wherein the host and the memory card lack the memory controller function, and
• wherein the memory card receives from the mother card through the second and first connectors program and erase voltages for respective use in storing data in, and erasing of data from, the array.
