2 Device Overview
3D NAND Flash: Gen3 X3 128Gb 2-Plane
Device Overview
The SanDisk® 3D NAND Flash: Gen3 X3 128Gb memory device
contains a single 128Gb device in a 48-pin TSOP package. All
possible configurations may not be available. For a list of current
part numbers, see "Marketing Part Numbers” on page 0, and
Figure 1 on page 3 for part number decoding.
This device supports a Toggle Mode interface speed of up to
100 MHz (200 Mbps) for DDR1, and up to 266 MHz (533 Mbps)
for DDR2.
Toggle Mode is a NAND Flash interface for high-performance
applications that support data-in (DIN) and data-out (DOUT)
operations on both the rising and falling edges of the data strobe
(DQS) signal.
Toggle Mode NAND implements “Double Data Rate” operation
which is backward compatible with the commands supported in
conventional SDR (Legacy Mode) NAND, and provides a high
data-transfer rate based on the high-speed Toggle Mode interface.
Differential signals (DQS, DQSn, REn, RE) are used in DDR2
Toggle Mode. Single-ended signals DQS and REn are used in DDR1
Toggle Mode.
NOTE: From this point on:
• Conventional SDR (single data rate) operation will be referred to
simply as “SDR.”
• Single-level-cell (SLC) and three-level-cell (TLC) operation are
most often referred to by their respective acronyms, SLC and
TLC. The term three-bits-per-cell (3bpc) may also occur and is
used interchangeably with TLC.
