Apparatuses, systems, and methods for managing metadata storage at a memory

A method comprising:

• during a read operation at a memory to retrieve read data and metadata associated with a column address:
• decoding a subset of less than all of the bits of the column address to determine a metadata column address and a metadata column plane address corresponding to a particular one of a plurality of column planes of a memory array of the memory;
• during a first cycle of a double access cycle, providing the metadata column address as a first cycle address to the memory array to cause first cycle data to be retrieved from the memory array, wherein the metadata is included in the first cycle data;
• and
• during a second cycle of the double access cycle, providing the column address as a second cycle address to the memory array to cause the read data to be retrieved from the memory array.

A method comprising:

• during a write operation at a memory to store write data and metadata associated with a column address:
• decoding a subset of less than all of the bits of the column address to determine a metadata column address and a metadata column plane address corresponding to a particular one of a plurality of column planes of a memory array of the memory;
• during a first cycle of a double access cycle, providing the column address as a first cycle address to the memory array to cause write data to be stored at the memory array;
• and
• during a second cycle of the double access cycle, performing a read-modify-write operation by providing the metadata column address to the memory array to cause second cycle data to be read from the memory array, a selected portion thereof identified by the metadata column plane address to be modified with the metadata, and to be written back to the memory array at the metadata column address.
