Description
Technical field
The utility model relates to the data recovery technique field, particularly a kind of NAND Flash chip intelligent analytical equipment.
Background technology
Flash memory (FLASH) device is based on the integrated circuit (IC) chip that semiconductor technology is made, the excellent properties such as have antimagnetic, antidetonation, moisture resistance, volume is little.As the digital storage chip of the large capacity of solid storage medium, according to traditional magnetic recording and optical disc memory, NAND FLASH device has the machinery-free structure, can be repeatedly erasable, speed is fast, the remarkable advantage such as low in energy consumption, present (the USB flash disk for example in the mobile storage field, the MP3 player, digital memory card, solid state hard disc etc.) and in the built-in applied system become incontrovertible leading role.
The product that these Flash storage chips are relevant all can relate to the Flash bus signals.The Flash bus signals refers to: all set that control and data signal on the Flash storage chip.The product relevant for the Flash storage chip can relate to the bus signals problem analysis.The general method that adopts is to use traditional testing tool at present, such as logic analyser, oscillograph etc.The testing tool that these are traditional, can be used as normal signal to the Flash bus and carry out sampling and analyzing, but such sampling and analyzing lacks specific aim, so need to realize by following two steps when analyzing the Flash bus signals: the sampling of (1) Flash storage chip bus signals; (2) Flash storage chip bus signals is analyzed.
Adopt the universal test instrument that the Flash bus signals is sampled, not only signal sampling is very inconvenient, and because the restriction of storage depth, the semaphore that obtains also is very limited.Signal analysis process is with the signal after the sampling, by comparison Flash bus signals interface protocol, signal interpretation is become the bus messages such as order, address, data of Flash.This process generally need to manually be finished owing to lacking the support of professional tool.
For some higher requirements, the harmony, the Flash that wipe such as Flash read and write distribution situation etc., almost can't realize in addition.For the analysis of Flash storage chip bus signals, not only need Flash storage chip bus signals is extracted, and these signal resolutions need to be become the bus message such as order, address, data of Flash to reflect intuitively.Along with the continuous expansion of Flash storage chip application, the demand of analyzing for Flash storage chip bus signals also increases thereupon.For adopting the universal signal testing tool to realize the analysis of Flash storage chip bus signals, more and more can't satisfy such demand.
