Are you sure 24LS256?
Not 24LC256?

What manufacturer? What package?. What marking?

I also have never heard of 24LS256 but maybe it's a code used by some small fabrication company. I would guess it would be the same specificaton as 24LC256 which is commonly available.

Are you sure it's an EEPROM? There is a 74LS256 but that's a TTL latch device.

THats just an antique LS TTL version of the now CMOS version 24LC256

24LS meant LS memory in the 80's and I guess mine is still working.

It should be 24LC256 and not 24LS256. From where you have find the part number?

Interesting, I actually have a few of these in the parts bin. I always thought they were cheap Chinese knockoffs with a slight misspelling. I still occasionally see large lots of the 24LS256 offered for sale on the wholesale Chinese semiconductor marketplaces.

I think an 'LS' (= bipolar Low power Shottky) version of such a dense memory is unlikely but smaller manufacturers often change the letters to 'customize' a standard part so it sound like their proprietary design. I would guess the 'LC' data sheet covered this device.
