1. 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 saving power with separated DQ voltage. For
applications that require high capacity and high performance NAND, Toggle DDR NAND is the most appropriate.
Toggle DDR1.0 NAND supports the interface speed of up to 100 MHz, which is faster than the data transfer rate
offered by SDR NAND. Toggle DDR NAND transfers data at high speed using DQS signal that behaves as a clock,
and DQS shall be used only when data is transferred for optimal power consumption.
This device supports both SDR interface and Toggle DDR interface. When starting, the device is activated in SDR
mode. The interface mode can be changed into Toggle DDR interface utilizing specific command issued by the Host.
1.2. Definitions and Abbreviations
SDR
Acronym for single data rate.
DDR
Acronym for double data rate.
Address
The address is comprised of a column address with 2 cycles and a row address with 3 cycles. The row address
identifies the page, block and LUN to be accessed. The column address identifies the byte within a page to access.
The least significant bit of the column address shall always be zero.
Column
The byte location within the page register.
Row
Refer to the block and page to be accessed.
Page
The smallest addressable unit for the Read and the Program operations.
Block
Consists of multiple pages and is the smallest addressable unit for the Erase operation.
Plane
The unit that consists of a number of blocks. There are one or more Planes per LUN.
Page register
Register used to transfer data to and from the Flash Array.
Cache register
Register used to transfer data to and from the Host.
Defect area
The defect area is where factory defects are marked by the manufacturer. Refer to the section 3.2
Device
The packaged NAND unit. A device may contain more than a target.
