Non-volatile memory storage device including an interface select switch and associated method

A device comprising

• an Advanced Technology Attachment (ATA) storage interface to convert data in accordance with an ATA protocol;
• a Serial Advanced Technology Attachment (SATA) storage interface to convert data in accordance with a SATA protocol;
• a multiplexer to select one of the storage interfaces responsive to a selection signal;
• and
• a memory controller to prioritize access to non-volatile semiconductor memory, to scramble the converted data, and to mare an input digital signal stream to a signal stream with different statistical characteristics,
• where the selected storage interface is structured to convert data exchanged between the non-volatile semiconductor memory and a host external to the device;
• and
• where the non-volatile semiconductor memory includes one or more non-volatile memory chips, and any selected one of the ATA storage interface and SATA storage interface is commonly connected to the one or more non-volatile memory chips.

A method for providing access to a plurality of nonvolatile semiconductor memory devices via multiple interfaces, comprising:

• receiving a selection signal;
• selecting one of an Advanced Technology Attachment (ATA) storage interface and a Serial Advanced Technology Attachment (SATA) storage interface responsive to the selection signal;
• transmitting first data from a plurality of non-volatile semiconductor memory chips to a host responsive to the selecting;
• transmitting second data from the host to the plurality of non-volatile semiconductor memory chips responsive to the selecting;
• scrambling the second data within a memory controller;
• mapping an input digital signal stream to a signal stream with different statistical characteristics;
• and
• detecting and correcting errors in both the first data and the second data within the memory controller,
• where any selected one of the ATA storage interface and SATA storage interface is commonly connected to each of the plurality of non-volatile memory chips.
