NAND32GW3F4A
Description
1
Description
The NAND32GW3F4A is part of the single level cell (SLC), 4224-byte page family of non-
volatile NAND flash memories. The device has a density of 32 Gbits and combines four 8-
Gbit dice in a stacked device. The four 8-Gbit dice are coupled for access as two 16-Gbit
devices, each with its own Chip Enable and Ready/Busy pin. This means each 16-Gbit can
be driven independently using the relative Chip Enable pin. The device operates from a 3 V
power supply.
In addition, each 16-Gbit device has its own maximum number of bad blocks and its own
electronic signature code.
This document must be read in conjunction with the NANDxxGW3F2A datasheet, which
fully details all the specifications required to operate this 8-Gbit/16-Gbit flash memory
device.
The device is available in TSOP48 (12 × 20 mm) package and is shipped from the factory
with block 0 always valid and the memory content bits, in valid blocks, erased to ‘1’.
