3D Charge Trap NAND Flash Memories
ECS Transactions, 2016This chapter starts off with 2 vertical channel architectures named BiCS (Bit Cost Scalable) and P-BiCS (Pipe-Shaped BiCS), respectively. BiCS was proposed for the first time by Toshiba in 2007, and another version called P-BiCS was presented in 2009 to improve retention, source selector performances and source line resistance.

Modeling nand Flash Memories for IC Design
IEEE Electron Device Letters, 2008In this letter, we present a compact model of NAND flash memory strings for circuit simulation purposes. This model is modular and easy to be implemented, and its parameters can be extracted through a simple procedure. It allows accurate simulation of NAND flash memories with a limited computational effort, taking into account capacitive coupling ...

NAND Flash memories are the storage media used inside Solid State Drives (SSDs). Indeed, a single drive for enterprise applications can contain up to hundreds of Flash chips. Flash memories are non-volatile in the sense that they can retain the information even when powered off, but they wear out, i.e.

Radiation effects on NAND Flash memories
2010Electronic chips operating at sea level are constantly bombarded by a shower of high-energy neutrons, which originate from the interactions of cosmic rays with the outer layers of the atmosphere. The neutron flux changes with altitude, reaching a peak very close to the cruise altitude of airplanes, posing an even more serious threat to avionics.

NAND Flash memory became a standard semiconductor nonvolatile memory. Everyone in the world has widely used NAND Flash memory in many applications, such as digital camera, USB drive, portable music player, smartphone, and tablet-PC. The cloud data server started to use SSD (Solid State Drive) which was based on NAND Flash memory.

Nowadays, Solid State Drives consume an enormous amount of NAND Flash memories [1] causing a restless pressure on increasing the number of stored bits per mm2. Planar memory cells have been scaled for decades by improving process technology, circuit design, programming algorithms [2], and lithography.

Modeling NAND Flash Memories for Circuit Simulations
2007In this paper, we will present the basic structure and the parameter extraction procedure for a compact model of a NAND Flash memory string working in Spicelike circuit simulators. To the author knowledge, this is the first Spice-like model of a NAND Flash memory string. This model is modular and simple to be implemented.

3D Stacked NAND Flash Memories
2016Market request for bigger and cheaper NAND Flash memories triggers continuous research activity for cell size shrinkage. For many years, workarounds for all the scalability issues of planar Flash memories have been found. Some examples are the improved programming algorithms for controlling electrostatic interference between adjacent cells [6], and the
