  • Reliability Of Nand Flash Memory

    Reliability of NAND flash memory is more interesting than that of other semiconductor devices. Program and erase of NAND flash perform by electron injection and emission to/from floating gate (FG). There are several methods of electron injection and emission. For electron injection, there are two methods, namely channel hot electron (CHE) injection and Fowler-Nordheim tunneling (FN-t) injection. Data retention is degraded by electron and hole traps in tunnel oxide. Detrapping of trapped charges in tunnel oxide is a major root cause of Vt shift during the data retention test. Read disturb failure is mainly caused in the erase state after program/erase cycling stress. The stress-induced leakage current (SILC), which is generated by program/erase cycling stress, is major root cause for the read-disturb phenomena. The mechanism of erratic over program is considered to be an excess electron injection at hole trap sites in tunnel oxide.

  • Three-Dimensional Nand Flash Cell

    This chapter introduces major three-dimensional (3D) cells. The bit cost scalable (BiCS) cell has a new structure of the stacked control gate layers and vertical poly-silicon channel. The thinner poly-silicon channel can obtain the easier electrostatic control performed by the gate electrode over the thinner body and the smaller poly-silicon grains which reduce the impact on the channel current of statistical variation of smaller grain size configuration. Terabit cell array transistor (TCAT) has a similar structure of BiCS, with a vertical poly-silicon channel, stacked word lines, and a silicon nitride (SiN) charge storage layer of the surrounding gate SONOS cell. The chapter describes a process sequence of vertical gate NAND (VG-NAND) cell and proposes a dual control gate with a surrounding floating-gate (DC-SF) cell for 3D NAND flash memory. This structure allows to apply floating gate to a 3D stacked cell structure with minimal cell size and high coupling ratio.

  • Challenges Of Three-Dimensional Nand Flash Memory

    This chapter introduces several types of three-dimensional (3D) NAND flash memory cells. It first addresses the challenges of 3D NAND flash memory and discusses data retention issues. The data retention characteristic of SONOS cell has problems of quick charge loss and large Vt shift in retention bake because of charge detrapping through thinner tunnel oxide. The chapter presents the analysis results of program disturb in 3D NAND cells. The program disturb mechanisms of 3D NAND cells are much different from that of 2D NAND cells, because cell structure and array architecture are totally changed. The cell current is much decreased in the 3D NAND cell, because channel material is changed from crystal Si (substrate Si) to poly-Si. The chapter describes the new structure of the peripheral circuit under cell array. Finally, it discusses the future trend of the 3D NAND cell.

  • Conclusions

    The development of NAND flash memory started in 1987 in the R&D center of Toshiba Corporation. The target market was the replacement of magnetic memory, such as HDD, and so on. The first NAND flash memory cells of 1-m rule was8*F2 cell size by using a wide x-direction pitch of 4 m (4*F) because LOCOS isolation width was 3 m wide due to the limitation of the high-voltage operation. The reasons why the NAND flash memory was accepted to the emerging applications were a low bit cost, high reliability, high performance, and low power consumption. The power consumption of storage memory has been greatly reduced by using NAND flash memory, compared with magnetic memory of HDD. In the data center, SSD based on NAND flash memory can reduce the power consumption of an enterprise server, and replace HDD, because of low power operation in NAND flash memory and low cooling power.

  • Introduction

    A breakthrough in the field of nonvolatile memories was the invention of the flash memory, which is a new type of electrically erasable and programmable read-only memory (EEPROM). Flash memory application can be classified into two major markets. One is for code storage applications, such as PC BIOS, cellular phones, and DVDs. The NOR-type cell is best suitable for this market due to its fast random access speed. The other is for file storage applications, such as the digital still camera (DSC), silicon audio, the smartphone, and the tablet PC. The NAND-type cell is suitable for file storage market. NAND flash has become an explosive innovation and has greatly contributed to the improvement of the lives with the advent of convenient mobile equipment such as smartphones and tablet PCs. Data retention time after programming and erase cycling is a key of NAND flash reliability.
