The those wondering, as I did, what a "Glasgow device" is, it's not a broken bottle wielded by a strung-out heroin addict.<p>It's actually a Glasgow Interface Explorer.

According to the datasheet this is a 512MB (4Gb) 34nm SLC flash, die code M60A. Introduced in the late 2000s and apparently was produced until ~2 years ago. SLC is the easiest to read in this "ad-hoc" fashion but note that newer MLC/TLC/QLC flash is quite prone to read-disturb errors and there may also be a scrambing algorithm applied to the data, so you're likely to need knowledge of both that and the ECC format in order to recover the actual data stored; it's somewhat astounding that random correctable bit errors are basically considered a "normal" occurrence for these newer parts, depending entirely on ECC to compensate for their unreliability.<p>Also, saying "parallel NAND" is like saying "4-wheeled car". NAND flash with the standard parallel interface is the vast majority, found in basically every solid-state mass storage application.
