Apparatuses and methods for enhanced metadata support

A method comprising:

• writing a value to a mode register of a memory device to set a metadata mode of the memory device to one of a first mode or a second mode;
• accessing a first percentage of addresses of the memory array of the memory device to store data when the metadata mode is in the first mode;
• and
• accessing a second percentage of addresses of the memory array of the memory device to store data when the metadata mode is in the second mode, wherein the first percentage is greater than the second percentage.

A method comprising:

• writing a value to a mode register of a memory device to set the memory device in a first mode or a second mode;
• reading data and four bits of metadata from a memory array of the memory device while in the first mode;
• and
• reading data and eight bits of metadata from a memory array of the memory device while in the second mode.

A system comprising:

• a memory device comprising:
• a mode register configured to store a value, wherein based on the value the memory device operates in a first mode or a second mode;
• a memory bank comprising a first plurality of column planes, a second plurality of column planes, and an extra column plane;
• and
• a column decoder configured to store data in a selected one of the first or the second plurality of column planes, parity bits in a non-selected one of the first or the second plurality of column planes, and metadata in the extra column plane as part of an access operation in the first mode and store data in the selected one of the first or the second plurality of column planes, parity bits in the non-selected one of the first or the second plurality of column planes, and metadata at least one of the non-selected one of the first or the second plurality of column planes or the extra column plane as part of an access operation in the second mode;
• and
• a controller configured to write the value to the mode register to set the memory in the first mode or the second mode.
