Abstract

一种存储控制器、存储控制方法、固态硬盘及存储***，该存储控制器包括：处理器，以及分别耦合至处理器的第一接口及存储器。第一接口，用于接收数据写指令，该数据写指令用于请求向第一逻辑地址写入目标数据。处理器，用于从存储器中读取第一逻辑地址对应的热点属性，在该热点属性指示第一逻辑地址为热点地址时，该处理器还用于将目标数据存储至存储器的第一区域。其中，该第一区域用于代替存储控制器所控制的闪存中与热点地址相对应的存储空间存储数据。该存储控制器在避免某些极小LBA区域被频繁写入从而保证固态硬盘寿命不受影响的同时，无需主机侧的参与，主机侧无需进行适配，因此可以极大降低主机与固态硬盘的耦合度。
