Abstract: A method of operating a memory device includes writing initial data to non-volatile memory cells of a non-volatile memory cell array, generating a difference value based on a difference between first data related to the initial data written to the non-volatile memory cells and second data related to the initial data written to the non-volatile memory cells, comparing the difference value with a reference value, and generating and transmitting a status signal indicating that the initial data has been successfully written to a controller when the difference value is less than the reference value. The data may be randomized by the controller or the memory device.

Abstract: A method of operating a storage device which includes a non-volatile memory including a normal unit configured to store normal data and a swap unit configured to store swap data and a controller configured to control the non-volatile memory is provided. The method includes receiving the swap data and a unit selection signal for selecting the swap unit from a host; and processing the swap data according to a data processing policy of the swap unit and writing the processed swap data to the swap unit. The data processing policy of the swap unit may be different from a data processing policy of the normal unit.

Abstract: An embedded multimedia card (eMMC), and a method of operating an eMMC, determine whether a vendor mode is to be entered by parsing a command argument of a command received from a host or a pattern of write data received from the host; receive vendor mode attribute information for the vendor mode, based on a result of determining whether the vendor mode is to be entered; and performing a vendor mode operation in the vendor mode based on the vendor mode attribute information.

Abstract translation: 一种嵌入式多媒体卡（eMMC）和一种操作eMMC的方法，通过解析从主机接收的命令的命令参数或从主机接收到的写入数据的模式来确定是否输入供应商模式; 基于确定是否要输入供应商模式的结果，接收供应商模式的供应商模式属性信息; 以及基于供应商模式属性信息在供应商模式下执行供应商模式操作。
