Data modification based on matching bit patterns

摘要

A data storage device includes a memory and a controller. The controller is configured to identify groups of bits that match any bit pattern in a first set of bit patterns. Each of the groups of bits includes a first bit of first data, a second bit of second data, and a third bit of third data to be stored at the memory. The controller is configured, in response to determining that a count of the identified groups exceeds a threshold, to change multiple bits of the first data. Changing the multiple bits of the first data reduces a number of the groups of bits that match any bit pattern in the first set of bit patterns.

1. A method comprising:
in a data storage device including a memory that has a three-dimensional (3D) memory configuration, the data storage device further including a controller associated with operation of memory cells of the memory, performing:
identifying groups of bits that match any bit pattern in a first set of bit patterns, wherein each of the groups of bits includes a first bit of first data, a second bit of second data, and a third bit of third data; andin response to determining that a count of the identified groups exceeds a threshold, changing multiple bits of the first data,wherein changing the multiple bits of the first data reduces a number of the groups of bits that match any bit pattern in the first set of bit patterns.
