Abstract:
Apparatuses, systems, methods, and computer program products are disclosed for hybrid dual write. An apparatus includes a memory device comprising a plurality of single level cell blocks and a plurality of multi level cell blocks. An apparatus includes a hybrid writing component. A hybrid writing component includes a single level writing circuit that writes data to a plurality of single level cell blocks. A hybrid writing component includes a multi level writing circuit that copies data from a plurality of single level cell blocks to a plurality of multi level cell blocks. A hybrid writing component includes a grouping circuit that directs a single level writing circuit to write data corresponding to a first logical group to a set of single level cell blocks of a plurality of single level cell blocks. In response to a multi level writing circuit copying data from a set of single level cell blocks to a plurality of multi level cell blocks, a first portion of data from the set of single level cell blocks remains uncopied because the first portion of data is insufficient to fill an entire multi level cell block.
