NM29N16
16 MBit (2M x 8 Bit) CMOS NAND FLASH E²PROM
General Description
The NM29N16 is a 16 Mbit (2 Mbyte) NAND FLASH The
device is organized as an array of 512 blocks each consist-
ing of 16 pages Each page contains 264 bytes All com-
mands and data are sent through eight I O pins To read
data a page is first transferred out of the array to an on-chip
buffer Sending successive read pulses (RE low) reads out
successive bytes of data The erase operation is implement-
ed in either a single block (4 kbytes) or on multiple blocks at
the same time Programming the device requires sending
address and data information to the on-board buffer and
then issuing the program command Typical program time
for 264 bytes is 400 ms All erase and program operations
are internally timed
The NM29N16 incorporates a number of features that make
it ideal for portable applications requiring high density stor-
age These features include single 5V operation high read
write endurance (250k cycle) and low current operation
(15 mA during reads) The device comes in a TSOP Type II
package which meets the requirements of PCMCIA cards
The NM29N16 is suited for numerous applications such as
Solid State Drives (SSD) Audio Recording and Image Stor-
age for digital cameras
