PCMCIA memory extension cards
Unity
PCMCIA memory extension cards make it possible to extend the RAM memory
capacity of high-performance Quantum processors.
Depending on the model, these cards are designed to accommodate:
b
b
b
The cards fit into PCMCIA slots in the Quantum 140 CPU 651 p0/671 60 processors.
These cards provide three different storage types:
b
512 Kb to 4096 Kb: TSX MFP PpppK/M for Flash EPROM memories.
b
v
v
The limit between these 2 spaces is configurable. The configurable cards are:
v
v
Storage of additional data, provided by SRAM TSX MRP F004M/008M memory
cards with 4 or 8 Mb.
These cards use 2 technologies:
b
Used particularly in the application program design and debugging phases.
These cards provide:
v
v
The memory is protected by a removable battery built into the PCMCIA card.
A second auxiliary battery is present to enable the main battery to be replaced
without loss of data.
b
Used when debugging of the application program is complete. This is used to:
v
v
When in use, it is impossible to carry out modifications to the application in online
mode.
Only those extension cards with the program stored in SRAM memory TSX MRP
CpppK/M allow you to perform program modifications in online mode.
A user with a processor fitted with a memory extension card and who wishes to make
modifications or additions to the program in online mode must structure the
application program in several reasonably sized sections.
