Memory addressing methods and associated controller, memory device and host

Abstract

A method for accessing a secure digital (SD) card includes: a voltage supply pin for voltage supply from a host, at least one ground pin, a clock pin for a clock signal from a host, a command pin for a command from a host, and four data pins for writing data into the SD card or reading data from the SD card. The method includes receiving an address extension command including a first address, receiving an access command including a second address, and accessing at least a memory location of the SD card indicated by a third address, which is a combination of the first address and the second address. The access command indicates an access operation to be performed on the SD card selected from: a single read operation, a single write operation, a multiple read operation, a multiple write operation and an erase operation.
