Paragraph Number

284

In one embodiment, the LSB corresponds to a lower page of data and the MSB corresponds to an upper page of data. In certain embodiments, the multi-level storage cell may adhere to a two-phase programming model, described below, which requires that the LSB be written to before the MSB can be written or vice versa. In another embodiment, the LSB and MSB may be programmed separately by the solid-state storage controller 104. Such an approach may be taken due to vendor or manufacturer requirements for page pairing (i.e., a LSB bit of MLC cell is paired with an MSB bit of a different MLC cell) and page addressing (i.e., LSB page must be programmed before the MSB page or vice versa). In certain instances, the LSB must be written before the MSB is written, the MSB must be written before the LSB is written, or the like.
