Abstract
Apparatuses, systems, and methods for separate write enable signals for data, metadata, and parity information. A memory array is divided into column planes and an extra column plane. In modes of the memory device, data and parity information is stored in the column planes and metadata is stored in the extra column plane. The extra column plane includes separate write enable signals (or separate states of a single signal) which activate different portions of the bit lines (e.g., even and odd bit lines). In an access operation, a column select signal is provided to the extra column plane along with one or the other write enable signals such that fewer than all of the bit lines activated by the column select signal provide data.
