Cypress vs. GSI Battle Following Rambus Lead

The current battle between Cypress Semiconductor and GSI Technology caught The Memory Guy’s eye recently. Many readers may have missed this battle that commenced when Cypress filed a Federal Trade Commission (FTC) lawsuit in the US in which the company asked for GSI SRAMs to be barred from importation into the US because of a patent dispute.

GSI has issued a countersuit with a complaint of anticompetitive practices.

What garnered my interest is how similar the tactics in this lawsuit are to those used for some of the Rambus lawsuits that evolved over the years: Continue reading “Cypress vs. GSI Battle Following Rambus Lead”

The article was based on a press release from NEC and Tohoku University that can be read HERE.

It’s not at all surprising that the release was misunderstood – it’s very awkwardly written:

The new CAM utilizes the vertical magnetization of vertical domain wall elements in reaction to magnetic substances in order to enable data that is processing within the CAM to be stored on a circuit without using power.
