Systems and methods of shaping data

摘要

A method of shaping data includes receiving data represented as a first set of bits, where each bit of the first set of bits corresponds to a logical value. A first write current to write a first logical value to a storage element is less than a second write current to write a second logical value to the storage element. The method also includes applying a shaping operation to generate a second set of bits, where a proportion of bits having the first logical value is larger for the second set of bits than for the first set of bits. The method also includes writing the second set of bits to the memory.

1. A method comprising:
in a data storage device including a memory including a plurality of resistance-based storage elements, performing:
receiving data represented as a first set of bits, each bit in the first set of bits corresponding to a logical value, wherein a first write current to write a first logical value to a storage element in the memory is less than a second write current to write a second logical value to the storage element;applying a shaping operation to generate a second set of bits, wherein a number of bits having the second logical value is smaller for the second set of bits than for the first set of bits; andwriting the second set of bits to the memory.
