Abstract

Disclosed is a method to support below functions. 1. Write the data simultaneously which doesn't exist sequentially on buffer. 2. Handle "skip write" efficiently. (skip write write the data simultaneously which exists sequentially on buffer but of which LBA is not sequential.) In traditional way , above No1 was unrealizable. And bout No2 , overhead of microcode is too large. Because microcode has to check each LBA's flag(which indicates "this LBA should be write or not").
