Apparatuses and methods for reading and/or programming data in memory arrays having varying available storage ranges

摘要

Apparatuses and methods are disclosed, including methods for reading data from and programming data to an array of memory cells having varying available storage ranges. One such method involves determining a position of a determined value of a parameter within an available storage range of a selected memory cell of an array of memory cells.

主权项

1. A method for use with respect to an array of memory cells, wherein each memory cell of the array has a parameter that can be programmed to any value within an available storage range of the cell having a continuous range of available storage values, wherein the available storage range for at least one of the memory cells of the array has a different continuous range of available storage values than at least another one of the memory cells of the array, said method comprising:
determining a current value of the parameter of a selected memory cell of the array corresponding to one of the available storage values in the continuous range of available storage values within the available storage range of the selected cell; and determining a position of the determined value of the parameter within the available storage range of the selected memory cell.
