What type of RAM is this?

At an inspired guess it's made by Hyundai. That might help.

Thanks guys. Should have said that it's 28-pin surface mount. I THINK it's a standard 62256 ( 32K * 8 ) but am not 100% certain.

Going off at a tangent, what's a good, cheap, modern equivalent of the

Even though the part is marked as "HY62WT081E", the actual part number is "HY62WT08081E".

Here is a datasheet for the HY62WT08081E series:

Page 13 of the datasheet decodes the part number as ...

HY62WT081E = part name, 2.7~5.5V D = Low Low Power 55 = 55ns @ 4.5~5.5V, 70ns @ 2.7~3.6V C = Commercial (0 ~ 70 °C)

Excellent, many thanks for that. So why didn't the put complete number on the chip? For security purposes? It looks like the whole number could have been accomodated.

Much appreciated anyhow - looks like it's compatible with the 62256, etc.

When AdrianC posted the URL of the "Hynix part number decoder", I thought that your number was missing an additional "08" code for the capacity, so I searched for "HY62WT08081".

It may be instructive to see how other 8-bit Hynix SRAMs are marked.
