摘要：
A system, computer readable program, and method for programming flash memory, the method includes: providing multiple pairs of most significant bit (MSB) page uncoded bit error rates (UBERs) and least significant bit (LSB) page UBERs; selecting a selected MSB page code rate and a selected LSB page code rate so that a selected MSB page UBER associated with the selected MSB page code rate and a selected LSB page UBER associated with the selected LSB page code rate support a highest average UBER out of the multiple pairs of MSB page UBERs and LSB page UBERs, wherein the selected MSB page code rate and the selected LSB page code rate are obtainable under a desired code rate constraint; and determining an encoding and programming scheme that may be based on the selected MSB page UBER, the selected MSB code rate, the selected LSB page UBER and the selected LSB code rate.
