The data management device comprises an external communication interface unit communicated with at least one processor; an external storage interface unit for performing data access to at least one storage medium; and a controlling unit for controlling the operation of the external communication interface unit and the external storage interface unit. The invention also provides a data management method. The organizational management is performed to the semiconductor storage media in various electronic products by using the data management device, the data management device can be compatible with the prior and future continuously promoted various semiconductor storage media, the upgrading is simple, and the updating of the semiconductor storage medium is adapted without changing the interface design; the purpose that the external communication interface adopts logical mapping for addressing is realized; the implementing is easy and the large-scale production is convenient.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data management device and a management method based on a semiconductor storage medium. Background technique [0002] Now semiconductor storage media are mainly used in the fields of portable electronic products and embedded devices, and these products or devices need to store a large amount of data, especially video and audio data. As these products or devices are more widely used and more powerful, semiconductor storage media are also developing rapidly, and capacity, integration, production technology, technology, and media density are also increasing day by day. Different brands, models, The differences among semiconductor storage media in process, capacity and technology are getting bigger and bigger, and compatibility is becoming more and more difficult; Higher requirements are put forward for bad block management and data verification, data security, wear leveling, addres...

AI Technical Summary

Problems solved by technology

[0004]1. Unable to use a unified driver for different semiconductor storage media;

[0005]2. For various brands and models of storage media, a large number of tests are required to ensure the compatibility and support of the processor for semiconductor storage media, causing delays The product goes on the market, increasing the cost of the product;

[0006]3. Cannot guarantee support for semiconductor storage media that will be launched in the future, which increases the risk of product solutions and may cause disputes with users or suppliers;

[0007]4. Since the data verification work is mainly done by hardware, the difficulty of data verification increases so that the processor needs to continuously update the design to complete the data verification work; However, the upgrade of existing processors is expensive and requires a long cycle, which cannot meet the requirements of cost control and rapid market response
