ABSTRACT




The ATmega16 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega16 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic ....etc

Abstract Even though their capacities are still orders of mag- nitude lower than those of hard disks, flash storage sys- tems are rapidly gaining importance in energy-constrained systems. This paper focuses on USB flash drives, which can provide portable storage to mobile systems or stor- age to systems that otherwise do not have persistent stor- age opportunities (e.g., low-power sensor devices). The paper presents studies relating to power consumption, en- ergy overheads and benefits, and performance impacts of USB flash drives. The key insig ....etc

FLASH MEMORY


Presented by
Rajnikant Bal
Roll no:IT200118159

Under the Guidance of
Mr. Pradeep Kumar Jena.



abstract

Flash memory is erased in sections whose sizes and locations in the chip are defined by the part’s manufacturer.
As a result, once a flash memory location is programmed, the entire section containing the location must be erased before that location can be programmed again.

8-bit Microcontroller with 8K Bytes In-System Programmable Flash


Description
The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K
bytes of in-system programmable Flash memory. The device is manufactured using
Atmel’s high-density nonvolatile memory technology and is compatible with the industry-
standard 80C51 instruction set and pinout. The on-chip Flash allows the program
memory to be reprogrammed in-system or by a conventio ....etc

A flash mob computing (also flash mob computer) is a temporary ad-hoc computer cluster running specific software to coordinate the individual computers into one single supercomputer. A flash mob computer is distinct from other types of computer clusters in that it is set up and broken down on the same day or during a similar brief amount of time and involves many independent owners of computers coming together at a central physical location to work on a specific problem and/or social event. Flash mob computer derives its name from the more gene ....etc

INTEREST in nitride-based localized trapping storage Flash memory cells has revived for 10-min-cell operation, which can double the memory density. Besides, they also show better scalability since charges are stored in nitride traps rather than a poly silicon floating-gate in conventional Flash memory cells. Nitride storage memories do not have floating-gate-induced drain turn-on and coupling issues, which are believed to be the scaling limitations of conventional floating-gate memories .Various operation schemes were proposed based on the nitr ....etc

Introduction

In computer operating systems, demand paging is an application of virtual memory. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it (i.e., if a page fault occurs). This is an example of lazy loading techniques.

The compressed ROM file system (or cramfs) is a free read-only Linux file system designed for simplicity and space-efficiency. It is mainly used in embedded systems and small-footprint systems. Unlike a compressed image of a ....etc

1. Description
The AT89C55WD is a low-power, high-performance CMOS 8-bit microcontroller with 20K bytes of Flash programmable read only memory and 256 bytes of RAM. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry standard 80C51 and 80C52 instruction set and pinout. The on-chip Flash allows the program memory to be user programmed by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C55 ....etc
