SELECTIVE ACTIVATION OF PROGRAMMING SCHEMES IN ANALOG MEMORY CELL ARRAYS

摘要

A method for data storage includes defining a first programming scheme that programs a group of analog memory cells while reducing interference caused by at least one memory cell that neighbors the group, and a second programming scheme that programs the group of the analog memory cells and does not reduce all of the interference reduced by the first programming scheme. One of the first and second programming schemes is selected based on a criterion defined with respect to the analog memory cells. Data is stored in the group of the analog memory cells using the selected programming scheme.

1. An apparatus, comprising:
a plurality of memory cells; and a control circuit configured to:
receive data for storage in the plurality of memory cells;store a first portion of the received data using a first programming scheme that requires a first period of time to store the first portion of the received data;select a second programming scheme responsive to an evaluation of a criterion, andstore a second portion of the received data using the second programming scheme, wherein the second programming scheme requires a second period of time to store the second portion of the received data;wherein the first period of time is less than the second period of time.
