INTRODUCTION TOSHIBA CONFIDENTIAL Tx58TEGxDCJTAx0 1.1. 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 savin [ ... ]
