an IBM 128MB 100MHz type CL2 Synch memory chip.  Why do you ask?

Commented:
It's PC ram (the stuff that was used before DDR)
With a speed of 100 MHz, and a timing of 2 CAS.
Made by (for) IBM.

If you are interested, this is a good start:

That is a 128mb PC100  SDRAM SODIMM with a CAS (column address strobe) latency of 2.
This is an old, obsolete form of laptop memory.  Not sure but I think it came out around 1998.

exactly what JohnnyCanuck says..
SDRAM SODIMM PC100, 128mb stick
And as stated it is made by IBM.  It is laptop ram.
The FRU# is a part number for IBM.
