Embodiment Construction

[0070] The present invention proposes a data management method, which can rearrange data according to the storage state of the embedded memory storage device, thereby effectively using the storage space of the embedded memory storage device. In addition, the data management method of the present invention stores the predetermined data in a more stable fast physical page by using the burning mechanism, and then uses the restore mechanism to re-store the predetermined data in the fast physical page and the slow physical page, thereby being able to Avoid the data stored in the embedded memory storage device from generating error bits due to special environments, such as high temperature generated by welding. The present invention will be described in detail below with several exemplary embodiments and accompanying drawings.

Abstract

The invention provides a data management method, a memory controller and an embedded memory storage device. The embedded memory storage device is provided with a plurality of physical blocks, and each physical block is provided with a plurality of quick physical pages and a plurality of slow physical pages. The method comprises a step of detecting the state of a state marking unit. The method also comprises the steps of: automatically reading the stored data if the state of the state marking unit is marked as a first state, storing the data again by the quick physical pages and the slow physical pages of the embedded memory storage device, and marking the state of the state marking unit as a second state. Therefore, the storage space of the embedded memory storage device can be effectively utilized.

Description

technical field [0001] The present invention relates to a data management method, and in particular to a data management method for an embedded memory storage device, a memory controller and an embedded memory storage device using the method. Background technique [0002] The rapid growth of digital cameras, mobile phones, and MP3 players has led to a rapid increase in consumer demand for storage media. Since rewritable non-volatile memory (rewritable non-volatile memory) has the characteristics of data non-volatility, power saving, small size, no mechanical structure, and fast read and write speed, it is most suitable for these electronic products. An embedded Multi Media Card (eMMC) widely used in mobile phones is a storage device using flash memory as a storage medium. Therefore, the flash memory industry has become a very popular part of the electronics industry in recent years. [0003] In general, an embedded Multi Media Card (eMMC) used in electronic products is use...
