摘要：
A method for operating a memory controller is provided. The method includes generating a pseudo random number by using a seed included in a stored seed group corresponding to a page to be currently programmed, wherein the stored seed group is stored among a plurality of seed groups. Data to be programmed into the current page is randomizing by using the pseudo random number and the memory controller outputs the randomized data. A solid state drive (SSD) or other memory storage device such as a memory card includes the memory controller and includes a read only memory (ROM) storing the plurality of seed groups. The memory controller includes a micro-processor and a read only memory (ROM) storing executable code for causing the micro-processor to access the plurality of stored seed groups and to select a seed therefrom corresponding to a page to be currently programmed.
