Patent number 10319907:Non-filamentary = no need for error...

Patent number 10319907:

Non-filamentary = no need for error correction = DRAM like speed. Is what sets 4ds apart and why Western Digital has partnered with 4ds for so long.

Note the second last paragraph of the Patent:

The speed or access time of memories using an array of memory devices as described herein is much better than that of memories which use traditional non-volatile memory cells. This is the case at least because the electrical resistance of the layers and contacts outside of the memory layer is low, as discussed above with reference to each of the layers and contacts. Memory speed using memory devices as described herein is also improved over traditional memories because large memory systems using memory devices as described herein may be operated without speed crippling Error Correction Code (ECC) techniques as a result, for example, of reliable retention of the memory states of the memory devices. For example, memory systems having Megabyte, Gigabyte, Terabyte storage may be operated without speed crippling ECC techniques.
