3D NAND flash has many inherent advantages over 2D (planar) flash that go beyond density alone. 3D NAND flash can be programmed faster than 2D can. Spaces between memory cells on 3D flash are far wider than in 2D NAND flash memory. This makes it possible to improve the programming speed and at the same time reduce power consumption by increasing the amount of data for a single programming sequence. The wider open spaces between cells also decreases cell coupling providing greater reliability and endurance in comparison to 2D NAND flash memory. The TR200 pairs Toshiba's 2-channel TC58 controller with a third generation Toshiba BiCS 3D flash array. BiCS 3D flash will only come in TLC (3-bit) or QLC (4-bit) flavors, there will be no MLC (2-bit) variants. Toshiba is confident that the performance and endurance offered by BiCS 3 is at minimum on par with planar MLC flash. Just as we no longer see new retail SLC flash products brought to market, the day is coming sooner rather than later where we may no longer see new MLC flash products hitting store shelves. Third generation BiCS (BiCS 3) 3D TLC flash products are starting to enter the mainstream market. Toshiba's 64-Layer BiCS 3 TLC flash technology is well refined and set to shake up the market by offering better endurance, higher density, and higher performance TLC flash than is possible from conventional planar (2D) TLC flash technology.
