Hybrid storage system employing reconfigurable memory

A system comprising:

• a memory controller in communication with a memory, the system configured to perform a method comprising:
• comparing a number of memory blocks in a first pool of free memory blocks in the memory to a threshold, the memory including memory blocks logically divided into the first pool of free memory blocks, a second pool of memory blocks and a third pool of memory blocks;
• and
• expanding the first pool of free memory blocks based on determining that the number of memory blocks in the first pool of free memory blocks is less than the threshold, the expanding including:
• selecting a first memory block from the second pool of memory blocks, the first memory block comprising active and non-active content;
• selecting a second memory block from the third pool of memory blocks;
• copying the active content of the first memory block to the second memory block;
• erasing the first memory block;
• and
• adding the first memory block to the first pool of free memory blocks.

A computer program product for storing data in memory, the computer program product comprising:

• a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
• compare a number of memory blocks in a first pool of free memory blocks in the memory to a threshold, the memory including memory blocks logically divided into the first pool of free memory blocks, a second pool of memory blocks and a third pool of memory blocks;
• and
• expand the first pool of free memory blocks based on determining that the number of memory blocks in the first pool of free memory blocks is less than the threshold, the expanding including:
• selecting a first memory block from the second pool of memory blocks, the first memory block comprising active and non-active content;
• selecting a second memory block from the third pool of memory blocks;
• copying the active content of the first memory block to the second memory block;
• erasing the first memory block;
• and
• adding the first memory block to the first pool of free memory blocks.
