Host for controlling non-volatile memory card, system including the same, and methods operating the host and the system

Abstract

A host for controlling a non-volatile memory card, a system including the same, and methods of operating the host and the system are provided. The method of operating the host connected with the non-volatile memory card through a clock bus, a command bus, and one or more data buses includes transmitting a first command to the non-volatile memory card through the command bus, transmitting first data corresponding to the first command to the non-volatile memory card through the one or more data buses or receiving the first data from the non-volatile memory card through the data buses, and transmitting a second command to the non-volatile memory card at least once through the command bus during or before transfer of the first data.

What is claimed is: 
     
         1 . A method of operating a host connected to a non-volatile memory card:
 transmitting a first command from the host to the non-volatile memory card through a command bus, the first command indicating first data;   transferring the first data by performing at least one of,
 transmitting the first data from the host to the non-volatile memory card through one or more data buses, and 
 receiving, at the host, the first data from the non-volatile memory card through the one or more data buses; and 
   transmitting a second command to the non-volatile memory card through the command bus during or before the transfer of the first data.
