Abstract: The present invention provides a flash memory controller for mapping the logical addresses to the physical addresses of memory including a plurality of blocks, each having a plurality of pages, wherein the memory controller includes a processor. The processor includes hot page decision unit and an address translation unit. The hot page decision unit classifies pages in each block into hot pages and cold pages based on a predetermined criterion.

In the presence of polyphenol oxidase, a bioactive molecule containing a phenol or catechol group can be simply in situ oxidized within a short time to dopa or dopaquinone which forms a coordinate bond with a metal or polymer substrate, thus immobilizing the bioactive molecule onto the surface with stability. Based on the surface immobilization of bioactive molecules using polyphenol oxidase, various bioactive molecules such as osteogenetic peptides and growth factors can be simply immobilized to medical metal or polymer substrate surfaces such as orthopedic or dental implants which can be then effectively used to induce rapid osteogenesis after being transplanted. Also, antithrombotic agents and/or entothelialization inducing agents may be immobilized to medical substrates for vascular systems, such as stents and artificial blood vessels, thus guaranteeing hemocompatibility to the medical substrates.
