Ah yes, now I remember ... indeed it was even 3 power supply voltages,
like the old 4116 DRAMs.
Thanks Tony, a few failing memory bits are corrected :-)

You're thinking of the 2K byte (16K bit)  EPROMs. Everybody but TI made a
2716 that was single-rail (+5V supply only). TI's 2716 was a 3-rail part
(+5V, +12V, -5V), the TI 2516 was single-rail part and much the same as
everyone else's 2716.
