General Description
   Toggle DDR is a NAND interface for high performance applications which support data read and write operations using bidirectional DQS.
   Toggle DDR NAND has implemented ’Double Data Rate’ without a clock. It is compatible with functions and command which have been supported in conventional type NAND(i.e. SDR NAND) while providing high data transfer rate based on the high-speed Toggle DDR Interface and saving power with separated DQ voltage. For applications that require high capacity and high performance NAND, Toggle DDR NAND is the most appropriate.
