Embodiment Construction

[0033] The application of the flash memory chip bus signal analysis tool of the present invention is very simple, as long as the flash bus signal sampling probe (eg connector, wire, probe, etc.) of the present invention is directly connected to the corresponding flash bus signal. That is to say, the present invention only needs to include two parts in practical application:

[0034] (1) The analyzed object related to the Flash memory chip.

[0035] (2) Flash bus signal analysis tool.

[0036] In order to achieve such a requirement, the Flash bus signal analysis tool must have the following five functions:

[0037] (1) Sampling the Flash bus signal of the object to be analyzed, the Flash bus signal analysis tool is connected to the Flash bus signal of the object to be analyzed through sampling probes (such as connectors, wires, probes, etc.), and according to a certain frequency ( Generally greater than twice the frequency of the Flash bus) to sample it.

[0038] (2) Analyze...

Abstract

The invention discloses a bus signal analyzing tool of a Flash storage chip, which comprises a Flash bus signal sampling unit, a Flash bus signal analyzing unit, a Flash bus signal display unit, a Flash bus signal storage unit and a Flash erasing harmony analyzing unit, wherein the Flash bus signal sampling unit, the Flash bus signal display unit, the Flash bus signal storage unit and the Flash erasing harmony analyzing unit are respectively connected with the Flash bus signal analyzing unit, and the Flash bus signal storage unit and the Flash erasing harmony analyzing unit are respectively connected with the Flash bus signal display unit. Compared with the traditional testing tool, in the aspect of analyzing bus signals of the Flash storage chip, the invention has great progress and obvious advantages, the building and analyzing environment is very simple, the operation is simple and convenient, and the storage depth is large.

Description

technical field [0001] The invention relates to related products of Flash memory chips, in particular, to a bus signal analysis tool for Flash memory chips. Background technique [0002] Flash memory chips are widely used in various fields, such as SD cards, U disks, SSD hard drives, etc. These products related to Flash memory chips all involve Flash bus signals. Flash bus signal refers to: the collection of all control and data signals on the Flash memory chip, such as figure 1 Shown is an application model of a Flash memory chip. It can be seen from this figure that the Flash controller is connected to the Flash memory chip through a group of buses, and this group of buses is the Flash bus. Among them, IO0~IO7 are the data signal lines, and the Flash controller sends commands, addresses, data and received data to the Flash memory chip through these data signal lines; CE, Busy, ALE, CLE, WP, WE, RE are the Flash controller and Flash. Control signal lines between memory ...
