    \$\begingroup\$ Yes, IDT is the manufacturer. Very good parts, I designed IDT into many circuits in the late '80s and early '90s. Their FCT logic gates were very fast, altho static sensitive. Had to use ESD mats and be strapped to the mat when handling bare components. \$\endgroup\$ – CrossRoads Apr 23 at 13:10

From what I could find, the manufacturer is Integrated Device Technology (hence the integral sign, it's part of their logo).

The chip is most likely the 7164 series asynchronous static RAM.

  • \$\begingroup\$ Thanks for the quick response, is it still possible to purchase these chips or an equivalent? \$\endgroup\$ – Fish5001 Apr 24 at 10:37
  • \$\begingroup\$ @Fish5001 Not sure what country you are in, but Digikey seems to have them in stock. \$\endgroup\$ – Egor Tamarin Apr 24 at 10:41
