July 16 (Reuters) - A federal jury in Waco, Texas said on Thursday that Japanese chipmaker Kioxia 285A.T owes satellite-communications company Viasat VSAT.O $229 million for infringing a patent covering computer memory technology, according to a court document.

• The jury determined that Kioxia's flash-memory devices violate Viasat's patent rights in technology that allows such devices to consume less power and improves their reliability and longevity.

• Spokespeople for the companies did not immediately respond to requests for comment on the verdict.

• Carlsbad, California-based Viasat said it developed improvements to flash-memory technology – which stores data on transistors using electrical charges – while designing error-correction systems for satellites.

• Viasat alleged that Kioxia's flash-memory devices include error-correction technology that works in the same way as its patented technology.

• Kioxia denied the allegations and argued that the patent was invalid.

• Viasat has brought similar allegations against data-storage company Western Digital WDC.O in a separate lawsuit that is still ongoing.
