Samsung has launched a NAND flash chip with a NOR interface at
Electronica which it has called OneNAND.
"It combines the high data read speed (108Mbyte/s) with the
advanced data storage of NAND," said Samsung's vice-president
Werner Diesing. Billed as an 'ultrafast' device, the 1Gbit chip
actually has a 10Mbyte/s write.
This is slow compared to competitor Renesas, whose latest AND
chip has a 3Mbyte/s write/erase speed. Renesas has gone for high
speed write/erase because of the time it takes to write big
files such as photographs.
Asked about the relative slowness of the Samsung chip, Diesing
replied: "Big data files mean that erase time is an issue. So far
we've been focusing on the read speed, but we are working on the
erase side."
