Memory devices
From Wiki at Neela Nurseries
Before getting into specific parts, a couple of articles on NAND and NOR based flash memory types:

A part alternate to the MX...8035, two parts by Microchip. On Microchip's site there is mention that the SST26 prefixed part is recommended over the SST25, but did not see mention of end-of-life or other obsolescence at their site. Following are 16Mbit (2 Mbyte) and an 8Mbit (1 Mbyte) NOR flash memory:
