I have an Atmel AT28C256 32k x 8 parallel EEPROM (data sheet: http://www.jameco.com/Jameco/Products/P ... 4843AT.pdf ). I am trying to write to it, but nothing I do seems to work. The datasheet says it works just like an SRAM,

As far as I understand these chips can be connected like an SRAM, but to write them you have to perform a specific algorithm with writes to specific addresses (e.g. full page) then wait specific times etc. Those should be described in the data book, IIRC they are even different for different providers.
