| Abstract(in English) | In the presentation, a 1Tb 4b/cell 3D-NAND-Flash memory on a 176-tier technology with a 14.7Gb/mm2 bit density is shown with its innovative features. The die is organized using a 4-plane architecture for multiplane operations with a 16KB page size. The 4-plane architecture improves both program and read throughput, without increasing the die size. Periphery circuitry and page buffers are placed under the array using 5th-generation CMOS under Array (CuA) technology. To improve random read performance, a faster read is provided with a read concurrency feature, allowing four independent multiplane page read addresses. The programming operation is based on a 16-16 programming algorithm. The I/O transfer speed is 1600MT/s in ONFI4.2. |
