unknown SRAM chips

This IS your lucky day! Since nobody at all replied to my post offering several boxes of data books, I tossed 'em all out; HOWEVER, it turns out that I'd overlooked one box under a chair and guess what, it contained a 1986 Toshiba MOS memory book. The TMM2068 is a TTL compatible 4x4 NMOS SRAM:

 1-A7 20-Vcc
 2-A6 19-A8
 3-A5 18-A9
 4-A4 17-A10
 5-A3 16-A11
 6-A2 15-I/O1
 7-A1 14-I/O2
 8-A0 13-I/O3
 9-/CS 12-I/O4
10-GND 11-/WE

I think someone else already gave you the info on the HM6147

Anybody have pinouts for these ICs - I think they are some kind of SRAM.
