dimension in random access memory storage for subnotebooks
Swissbit starts delivery of the worldwide first
1 Gbyte Micro DIMM
Group has expanded its portfolio by DDR Micro DIMM memory modules
with 256 and 512 Mbytes as well as 1 Gbyte. The latter capacity
for the random access memory of subnotebooks is to date unique
worldwide and would not be possible without the technology applied
by Swissbit. Thanks to this technology it is possible to mount
the 16 chips required on one Micro DIMM PCB. The chip-on-board
and "die-stacking" technology applied additionally guarantees
high reliability and optimum temperature behaviour as a result
of improved thermal distribution.
subnotebooks are frequently used by business users whose applications
require a high level of storage capacity. Due to the low size
of the equipment and in comparison with other modules to the firmly
defined dimensions in all directions which are defined by the
Jedec standard, a maximum of development-engineering know-how
is required to increase the storage capacity. If the outer contours
of a Micro DIMM module do not comply exactly with the dimensions
required, that might lead to contact problems or even to a short
cut in the process of installing the module.
With the 1
Gbyte Micro DIMM Swissbit now advances to new dimensions. This
development is enabled by the so-called "die-stacking"
technology. The individual memory silicon chips, all originating
exclusively from renowned manufacturers are positioned on top
of each other on the PCB. The signal paths, however, all have
the same length. The chips are furthermore directly attached to
the PCB to enable an optimum heat dissipation via the PCB and
a better circulation of the air, as well as an excellent signal
quality. The same also applies to the DDR Micro DIMM memory modules
with 256 and 512 Mbytes.
The new 172-core
Swissbit Micro DIMM modules are compatible in full scope with
any Jedec standard and available with a storage speed of PC2700.
