128Mb MULTIBANK ASYNC/PAGE OR BURST FLASH
32Mb/64Mb ASYNC/PAGE CellularRAM COMBO
Device General Description
The MT28C128516W18/W30D, MT28C128532W18/
W30D and MT28C128564W18/W30D combination
Flash and CellularRAM devices are high-performance,
high-density, memory solutions that can significantly
improve system performance. This memory solution is
comprised of two 64Mb Flash devices and either a
16Mb, 32Mb, or 64Mb CellularRAM device.
It is important to note that the specifications con-
tained in this document supersede the specifications
listed in the referenced individual Flash and Cellular-
RAM data sheets.
For all asynchronous/page Flash devices, the Burst
mode specifications in the referenced Flash discrete
data sheet should be ignored, as they do not pertain to
asynchronous/page mode operation.
Each Flash memory features eight 4K-word sectors
(8 x 65,536 bits), designated as parameter blocks, and
the remaining part is organized in main blocks of 32K
words each (524,288 bits). The parameter blocks are
addressed either by the low order addresses (bottom
boot) or by the higher order addresses (top boot).
The two Flash devices can be supplied with any
combination of top or bottom boot (e.g., top/top, bot-
tom/bottom, top/bottom, or bottom/top). Please see
Figures 2 and 3 for more information.
CellularRAM General Description
The CellularRAM architecture features high-speed
CMOS, dynamic random-access memories developed
for low-power portable applications The CellularRAM
device is available in either 16Mb, 32Mb, or 64Mb den-
sities.
To operate seamlessly on a burst Flash bus, Cellular-
RAM products have incorporated a transparent self-
refresh mechanism. The hidden refresh requires no
additional support from the system memory controller
and has no significant impact on device read/write per-
formance.
The configuration register (CR) is used to control how
refresh is performed on the CellularRAM array. These
registers are automatically loaded with default settings
during power-up and can be updated any time during
normal operation. Special attention has been focused
on standby current consumption during self-refresh.
CellularRAM products include three system-acces-
sible mechanisms used to minimize standby current.
Partial array refresh (PAR) limits refresh to the portion
of the memory array being used. Temperature com-
pensated refresh (TCR) is used to adjust the refresh
rate according to the ambient temperature. The
refresh rate can be decreased at lower temperatures to
minimize current consumption during standby. Deep
power down (DPD) halts the refresh operation alto-
gether and is used when no vital information is stored
in the device. These three refresh mechanisms are
adjusted through the configuration register (CR).
For device specifications and additional documenta-
tion concerning CellularRAM, please refer to the
MT45W1MW16PAFA,
MT45W2MW16PFA,
MT45W1ML16PAFA,
MT45W2ML16PFA
MT45W4MW16PFA, and M45W4ML16PFA Cellular-
RAM data sheets at
www.micron.com/cellularram.
Flash General Description
The Flash architecture features a multipartition
configuration that supports READ-while-PROGRAM/
ERASE operations with no latency. A 4Mb partition size
enables optimal design flexibility.
Two Flash devices are stacked to achieve the 128Mb
density. Each Flash die has a dedicated CE# and OE#
control, enabling each Flash to be independently select-
able.
The stacked Flash devices enable soft protection for
blocks, as read only, by configuring soft protection reg-
isters with dedicated command sequences. For secu-
rity purposes, two user-programmable 64-bit chip
protection registers are provided for each Flash device.
The embedded WORD PROGRAM and BLOCK
ERASE functions are fully automated by an on-chip
write state machine (WSM). An on-chip device status
register can be used to monitor the WSM status and
determine the progress of the PROGRAM/ERASE tasks.
Each Flash device has a read configuration register
(RCR) that defines how the Flash interacts with the mem-
ory bus. For device specifications and additional docu-
mentation concerning Flash, please refer to the
MT28F644W18/W30 data sheet at
www.micron.com/
flash.
Flash Configurations
Each Flash memory implements a multibank archi-
tecture (16 banks of 4Mb each) to allow concurrent
operations. Any address within a block address range
selects that block for the required READ, PROGRAM, or
ERASE operation.
