1. A method, comprising:
receiving, at a memory device, data for storage at the memory device;
generating, at the memory device, a first plurality of syndromes based at least in part on receiving the data for storage at the memory device, the first plurality of syndromes associated with an error control operation for the received data, each syndrome of the first plurality comprising error correction or error detection syndrome bits;
storing, at the memory device, the first plurality of syndromes based at least in part on the error control operation;
retrieving, from the memory device, the data and the first plurality of syndromes based at least in part on storing the received data and storing the first plurality of syndromes;
generating, at the memory device, a second plurality of syndromes based at least in part on retrieving the data, the second plurality of syndromes associated with the retrieved data and the error control operation, each syndrome of the second plurality comprising error correction or error detection syndrome bits;
determining whether the first plurality of syndromes matches the second plurality of syndromes based at least in part on comparing the first plurality of syndromes and the second plurality of syndromes; and
storing, at a register of the memory device, an indication of whether the first plurality of syndromes matches the second plurality of syndromes.
