|Spansion Announces World’s First Single-chip 1 Gigabit NOR Flash
SUNNYVALE, CALIF. -Spansion LLC, the Flash memory venture of AMD and Fujitsu
Limited announced it is sampling the world’s first single-chip 1 gigabit (Gb) NOR Flash memory device to customers
in the embedded market. Based on 90-nanometer (nm) MirrorBit™ technology, the 1 Gb MirrorBit GL device is the
highest density, single-chip NOR Flash memory device on the market. It is designed for reliable code execution and
data storage in a wide range of embedded applications including automotive navigation systems, communications
infrastructure equipment, gaming and industrial control. The 1 Gb MirrorBit GL device is the first based on the
Spansion 90-nm MirrorBit process technology unveiled last month.
“Our innovative MirrorBit technology has
enabled us to reach this very important milestone, with a product that meets the density, quality, cost structure
and scalability needs of the diverse embedded market,” said Ian Williams, corporate vice president of marketing for
the Embedded Memory Division for Spansion. “High density single-chip NOR Flash memory products help customers lower
their design cost, enhance end product features, and ensure reliable, fast code execution. In addition, with this
added storage capacity, customers can leverage a single chip for both code execution and data storage.”
"Spansion's announcement of a 1 Gb 90-nm NOR device keeps the company in the density lead, where they have
been since last year's introduction of a 512Mb chip," said Jim Handy, Semico's Director of Nonvolatile Memory
Services. "It is important that they have designed this part and the family as a whole for the needs of the embedded
market, which often gets overlooked in favor of Flash chips for cell phones."
The 1 Gb MirrorBit
GL device extends the MirrorBit GL family, which also includes the industry’s only single-chip 512 megabit (Mb) NOR
Flash memory device in production. By scaling MirrorBit technology to 90 nm and doubling the density of its NOR
Flash memory, Spansion reduces component costs because it enables customers to use a single-chip device, instead of
multiple lower density discrete solutions or more costly multi-chip packages containing stacked lower density die.
Moreover, as an extension of its existing embedded product families, the device allows customers to easily migrate
to new high-density solutions, without having to engage in costly and complex system redesign.
Easier Migration with Spansion™ NOR Flash Memory Solutions
Spansion’s new 1 Gb device augments the
company’s broad product offering which includes densities ranging from 1 Mb up to 1 Gb. Backwards compatible with
previous generation products (down to the 2 Mb density), the device supports common software, pin-out and packaging
and can be rapidly deployed without requiring costly board redesign. The 1 Gb MirrorBit GL is package and pin-out
compatible with all MirrorBit GL-M (230 nm), MirrorBit GL-A (200 nm) and MirrorBit GL-N (110 nm) devices as well as
legacy Fujitsu and AMD LV family members (back to the 320 nm lithography). Packaging is also JEDEC-compliant.
Technical Features and Benefits of the 1G MirrorBit™ GL Product
The Spansion 1 Gb MirrorBit
product joins the Spansion GL family which includes densities ranging from 16 Mb up to 512 Mb – all in production
today. The 1 Gb MirrorBit GL operates at 3.0 volts (Vcc), features a random read speed of 110 nanoseconds (ns), and
offers a page read speed of 25 ns via an 8-word page buffer.
The new 1 Gb MirrorBit GL part
enables users to either execute code directly out of the Flash memory or shadow into DRAM at high speeds. The device
supports industrial temperature ranges from -40 to +85 degrees Celsius. The 1Gb MirrorBit GL uses a NOR architecture
that is designed to deliver 100 percent good sectors, eliminate the need for ECC and support a standard parallel
interface, reducing system complexity and cost.
requiring advanced security, Spansion supports Advanced Sector Protection (ASP) technology on the 1 Gb MirrorBit GL.
ASP provides robust and complete designer-defined security with 64-bit password protection for sensitive software
algorithms or parameters. The feature can be used by designers to store, lock and protect code or data stored on any
sector of the device, or assign an electronic serial number (ESN) to their product. In some applications,the central
office can use an ESN to identify their equipment remotely, control service levels and record access for billing
purposes. The feature can help prevent malicious attacks and viruses, as well as help prevent unauthorized use of
Availability, Packaging and Pricing
Spansion is providing samples of the 1 Gb
MirrorBit GL device now to a select group of customers. Production is slated to begin in late Q4. The part number
for the 1 Gb MirrorBit GL is S29GL01GP. The product is offered in 56-pin TSOP and 64-ball Fortified BGA packaging.
It will be priced at approximately $18.50 in quantities of 10,000.
