Memory Brand ID & Info ???

Anyone know anything about memory made by TA ?

I have three 512mb modules of pc2100 which I have not been able to find any information for.

The module labels show:
TA(logo) PC2100 DDR SDRAM
64M x 64 512MB
DDR DIMM

Hologram TA(logo) MEMORY
Genuine Product
Lifetime Waranty

labels on back side 512UDTZM3
barcode
serial number
barcode

The chips have the TA logo, the letters DAMC or DALE at upper left, 64MX4TI at lower left, 0305 at lower right, and a vertical 4 digit code at the right edge which is different on each chip (YNPX or ZC30 for example)

Any information will be much appreciated -- Thanks

Download and run cpuz and it will tell you all the info about your sticks of ram. Production dates/timings and such.
