Method and apparatus for relocating selected data between flash partitions in a memory device

A method of relocating selected data between partitions in a non-volatile storage device, the method comprising:

• reviewing information regarding a group of data stored in a low endurance type of non-volatile memory in the non-volatile storage device;
• determining in the non-volatile storage device if the information regarding the group of data stored in the low endurance type of non-volatile memory satisfies a heightened read probability criteria, wherein the read probability criteria identifies the group of data having a heightened probability of being read in a near operating future of the non-volatile storage device;
• and
• generating a second copy of the group of data in a high endurance type of non-volatile memory in the non-volatile memory device if the group of data satisfies the read probability criteria wherein a first copy is retained in the low endurance type of non-volatile memory and the second copy is simultaneously maintained in the high endurance type of non-volatile memory.

A non-volatile storage device for relocating selected data between partitions in the non-volatile storage device, comprising:

• a first type of non-volatile memory;
• a second type of non-volatile memory, the second type of non-volatile memory having a lower endurance than that of the first type of non-volatile memory;
• and
• a controller configured to:
• determine if data received at the first type of non-volatile memory satisfies heightened read probability criteria, wherein the heightened read probability criteria identify data having a greater probability of being read from the non-volatile storage device in a near term than an average read probability of data in the non-volatile storage device;
• and
• transfer the received data from the first type of non-volatile memory to a second type of non-volatile memory in the non-volatile storage device if the received data is determined not to satisfy the heightened read probability criteria.
