Visual Memory LLC launched a campaign with four suits, against Broadcom, Freescale Semiconductor, Marvell Semiconductor, and STMicroelectronics. One patent related to digital random access memory (DRAM) devices is asserted in each suit (5,654,932), and a second patent related to flash memory is asserted only against Marvell and STMicro (6,026,027). Microprocessor and flash memory products made and sold by the defendants are accused of infringing the patents-in-suit.
