This stuff is great!!!
2 gig memory sticks in Dimm or Simm format! Compatible with all current simm or dimm boards.
_____________________________________________
2048 X n Bit Random Access Write Only Memory.
Current Applications.
. Least significant control system's.
. Post mortem memory systems ( weapons guidance )
. Artifical memory systems.
. Non-intelligent micro controllers.
. First in - Never (FINO)out asynchronos buffers.
. overflow register ( bit bucket ).
Features.
. Fully encoded multi-port addressing.
. Write cycle time 3ns ( max typ)
. Read access times variable.
. Cell refresh times 2ns ( min typ ).
. TTL / DTL / CMOS compatible inputs.
. Clock input impedance 2pF max.
. VDD=0v + 3%, VCC=10v, VFF=6.3v AC.
Description.
The 20480 is a 2048 X n bit random access write only memory. Due to the employment of our proprietary Sadderson - Rabbet enhanced decepetion mode, which utilises both p and n channel MOS devices, the 20480 is capable of 50% higher speeds than you will be able to obtain. A single TTL level clock phase is required to drive the internal clock generator. The static memory cells are operated dynamically to yield an extremely low power dissipation, providing the Dimm is properly cooled. This is easily done with a 6ft fan placed 1/2" from the package. If the device fails you have exceeded the ratings, under these circumstances a larger fan is recommended. All inputs and outputs are directly TTL / DTL / CMOS compatible, providing the correct interfacing circuitry is employed. In any event the use of a 1 amp fuse in all supply and data lines is recommended.
The use of the the unique S3X process allows phenomal rates of production, thus ensuring the availability of this versatile package. All termianls are provided with slip on protectors, for the prevention of Voltage destruction ( pil packaged devices do not require protection ). The use of a low cost silicone Dimm package ensures reliability by the use of non-hermetic sealing, which prevents the capture of harmful ion's while allowing the free exchange of friendly ion's.
Notes:
1: Not applicable.
2: Measured at 1733Mhz.
3: Measured at 26mV with 1.9pF.
4: See other notes.
5: See modern production techniques by T.Arrieta. ( Not available yet ).

This stuff sounds great, I've order 4 of them at $500 each. Cheap for memory.
