Problems solved by technology

[0005] At present, most of the NandFlash on the market is a data channel with a bit width of 8 bits; based on this, for the main control of NandFlash, the data bit width of the basic channel is 8 bits; in order to pursue higher data transmission speed, the current research continues to increase the number of channels And optimize the software algorithm, but the increase in the number of channels increases the complexity of the software algorithm design

Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] refer to figure 1 , an embodiment of a multi-channel management method of the present invention is proposed. This management approach can include:

[0039] Step S10, configuring multiple sub-channels as wide channels through registers;

[0040] Step S11, controlling the wide channel and / or sub-channel to transmit and receive data.

[0041] In the multi-channel management method of this embodiment, a mapping relationship between data bits and channel bits can be established by binding some channels in the multi-channels into one wide channel. Wherein, each channel constituting the wide channel may be called a sub-channel of the wide channel. Timing synchronization for parallel operation of sub-channels in the wide channel.

[0042] The above-mentioned wide channels can be combined to correspond to several p...

Abstract

The invention discloses a management method and a management system for multiple channels. The management method comprises the following steps of: configuring a plurality of subchannels into wide channels through a register, and performing data transceiving through controlling the wide channels and / or the subchannels. According to the management method and the management system for the multiple channels, a control system for a software level can be simplified when the multiple channels are controlled, and the overall efficiency is increased.

Description

technical field [0001] The present invention relates to the technical field of multi-channel management, in particular to a multi-channel management method and management system. Background technique [0002] In large-capacity flash memory devices, as the number of channels increases, channel management will also become a part of system overhead (especially algorithm overhead), and will affect the overall performance of the system. [0003] If the single-channel independent management solution is used, since the control signals and data signals of each channel are independent of each other, the control process requires software intervention, which increases system overhead and requires high software design; at the same time, as the number of channels increases, The complexity of the software algorithm increases, and the workload also increases accordingly. [0004] In the current solid-state storage applications, multi-channel technology is used to improve the read / write / ac...
