RESPONDING TO CHANGES IN AVAILABLE POWER SUPPLY

Abstract:

Memories having a first pool of memory cells having a first storage density and a second pool of memory cells having a second storage density greater than the first storage density, and a controller configured to cause the memory to determine whether a value of an indication of available power of a power supply for the memory is less than a threshold, and in response to determining that the value of the indication of available power is less than the threshold, increase a size of the first pool of memory cells, limit programming of data received by the memory to the first pool of memory cells, and cease movement of data from the first pool of memory cells to the second pool of memory cells, as well as apparatus including similar memories.
