Overview:
While multi-level cell (MLC) flash has gained many design wins, especially in mobile handsets and other consumer electronics, issues such as performance and reliability remain. The latter is associated with the need for a high voltage for programming that causes noise and coupling problems. To overcome these reliability problems, flash manufacturers have adopted noble programming schemes and waveform analysis provides the details of the MLC NAND flash programming algorithm that each manufacturer uses for a particular device.
Armed with this form of internal analysis, done by probing various internal signals such as wordlines, bitlines, source lines, P-Well, etc, waveform analysis has proved to be a valuable tool from a competitive intelligence perspective as it shows how an exact operation/function can be implemented in multiple ways. Semiconductor Insights (SI) has analyzed two of the industry's leading NAND flash manufacturers latest 8-Gbit MLC NAND flash devices using these state-of-the-art waveform analysis techniques.
Use this OnDemand to compare Toshiba's programming approach to Samsung's, in particular:
