1. A method, comprising:
receiving, from a controller at logic of a memory device, a first set of bits comprising data and a second set of at least one bit indicating whether the first set of bits includes one or more erroneous or corrupted bits;
generating, at an encoder of the memory device, parity data associated with the first set of bits;
generating, at the logic of the memory device, modified parity data with the parity data and the second set of at least one bit, wherein:
in response to the second set of at least one bit indicating the data is poison data, the modified parity data comprises a summation of parity data and a poison pattern; and
the poison pattern indicates whether the first set of bits includes one or more erroneous or corrupted bits; and
writing the first set of bits and the modified parity data in an array of the memory device.
