A method and system for constructing a generator matrix is disclosed. The method includes: receiving a parity check matrix H, wherein the parity check matrix H includes multiple circulant sub-matrices; rearranging the parity check matrix H by column and row permutations to obtain a rearranged parity check matrix H′; and constructing the generator matrix G based on the rearranged parity check matrix H′.

An apparatus includes a plurality of memory dies and a controller. The controller may be communicatively coupled to the plurality of memory dies and configured to utilize multiple copies of a root record containing system data during a boot-up process. The multiple copies of the root record are stored using at least two of the plurality of memory dies.

摘要:
An electronic non-volatile computer storage apparatus and methods for reducing decoder error floor for such a storage apparatus are disclosed. An analysis process it utilized to study one or more performance metrics of a decoder of the storage apparatus in order to determine various endurance points throughout the lifetime of that particular type of storage apparatus. Theses endurance points indicate when different scaling factors should be applied and/or when log-likelihood ratio should be re-measured to accommodate physical degradations over time.

An apparatus includes a controller and an adaptive error correction code decoder. The controller may be configured to read data from and write data to a memory device. The controller may be further configured to write data in a two-step process, which includes (i) after writing data to a least significant bit (LSB) page, checking the data stored in the LSB page using a first strength error correction code (ECC) decoding process and (ii) after writing data to a most significant bit (MSB) page associated with the LSB page, checking the data stored in both the LSB and MSB pages using a second strength error correction code (ECC) decoding process.
