Numonyx™ StrataFlash® Cellular Memory (M18)
• Deep Power-Down (DPD) mode: DPD provides the lowest power consumption and
is enabled by programming in the Enhanced Configuration Register. DPD is initiatied
by asserting the DPD pin.

Configuration and Memory Map
The Numonyx™ StrataFlash® Cellular Memory device features a symmetrical block
architecture. The flash device main array is divided as follows:
• The main array of the 128-Mbit device is divided into eight 16-Mbit partitions. Each
parition is divided into eight 256-KByte blocks: 8 x 8 = 64 blocks in the main array
of a 128-Mbit device.
• The main array of the 256-Mbit device is divided into eight 32-Mbit partitions. Each
parition is divided into sixteen 256-KByte blocks: 8 x 16 = 128 blocks in the main
array of a 256-Mbit device.
• The main array of the 512-Mbit device is divided into eight 64-Mbit partitions. Each
parition is divided into thirty-two 256-KByte blocks: 8 x 32 = 256 blocks in the
main array of a 256-Mbit device.
• The main array of the 1-Gbit device is divided into eight 128-Mbit partitions. Each
parition is divided into sixty-four 256-KByte blocks: 8 x 64 = 512 blocks in the
main array of a 1-Gbit device.
Each block is divided into as many as two-hundred-fifty-six 1-KByte programming
regions. Each region is divided into as many as thirty-two 32-Byte segments.
