Commercialisation of the CMOX cross-bar memory technology of Unity Semiconductor has been postponed until 2014-2015.
In May 2009, the then CEO, ex-Micron exec Daniel Rinerson, told EW: "We see ourselves in the two year horizon for production volumes of our first product, a 64 Gigabit storage class memory."
This week, the current CEO, David Eggleston, told EW: “Commercialisation is for the 2014-15 timeframe.”
The plusses for CMOX is that it can be scaled “below 5nm”, though the smallest it has been scaled to is 30nm, and that a 1Tbit part could be made on a 45nm process using 32 memory layers.
There will be a cost advantage of using trailing edge processes in competition with those using expensive leading edge processes based on EUV and double patterning.
Eggleston sees a 1Tbit part as a leading edge device in 2015 because he expects the NAND people to slow down as they transition to vertical structures. The NAND people are already on 64Gbit.
