Toshiba goes to 64 layer flash with 3bit/cell

According to the company, the next target on its BiCS FLASH road map is a 1Tbyte product in which 16 dice will be stacked in one package. It says it plans to start sampling this part in April.

The 512Gbit device increases capacity per device by 65% compared to the 48 layer 256Gbit part, while reducing the cost per bit.
