I don't know what it is but I suspect old RAM or PROM.
And I don’t know this logo.
Someone can help me?

That's General Instruments' old logo:
No idea why there's a letter "E" next to it, but the SL-7-2064 p/n follows their usual numbering convention (aa-b-cccc).

Could be - although according to the link, SL7-2064 is an 8-pin DIP. (A dual 64-bit shift register, to be precise.) And the original manufacturer, of course, is General Instruments, as I said:

General Semiconductor is a different company altogether. Gotta be careful with these parts databases... A lot of the information is pretty sketchy.

Thanks.
I have 5 chips. Do you want one? |

Looks like that data sheet is at least partly correct...
SL = static shift register, > 50 bits/channel
7 = process (metal-nitride-semiconductor)
2064 = 2 channels, 64 bits each

So for this one, it's 2 channels, 50 bits each :
