Hello all,

We've received a reel of 1,000 SRAM parts from PartMiner that were deemed
counterfeit by the folks at Cypress. Due to availability issues in
March we were forced to buy from this broker, even though they've screwed
us in the past with counterfeit parts and I've pleaded with them not to
buy from them (or any broker) again. The failure rate of the chips at
initial test is about 10%. The chips in question are 256kb async SRAMS
marked:

CY7C199D-10VXI
0544 G 04
637944

After contacting Cypress, their response was:

"Based on the information (top marking) that you provided , our lot
history verification showed that it is "not" a Cypress device. Please be
guided that Cypress guarantees only parts that were bought from Cypress or
authorized distributors. Attached is the official Cypress Broker Letter."
