Abstract
Devices and methods that generate code on chip-kill parity in which the code is generated and shortened using variable node degree information for improved decoding of data. In one aspect, memory controller comprises an encoder configured to construct a first code of D data bits and P parity bits, determine the number of distinct variable degree nodes L and the number of data bits of each of the variable degree nodes in the first code, and construct a second code that is shorter than the first code based on the determined number of variable degree nodes and the number of data bits of each of the variable degree nodes in the first code.
