4DS Memory (ASX:4DS) completed the characterization and testing of the fifth platform lot, which de-risks the manufacture of the 20-nanometer memory cell array incorporated in the sixth platform lot, according to a Wednesday Australian bourse filing.

A memory array is used in storing large amounts of data.

The 20-nanometer memory cell array is expected to be manufactured and analyzed in the first half of the year, the filing said. This will position the 4DS ReRAM technology as a potential generational memory.
