Dynamic Memory Architecture is Uniden's implementation for storing and organizing systems, sites, groups, channels, and talkgroups in a scanner.
A scanner that implements Dynamic Memory Architecture has a pool of memory to store any programmed data. The pool is divided into blocks.
A system is the top-most element that can be created in DMA. Within each system, a number of Groups can be created. Within each Group, a number of Channels (for a conventional System) or Talkgroups (for a trunked System) can be created.
Some scanners also allow multiple Sites to be programmed for a trunked System.
Each System, Site, Group, Channel, or Talkgroup will occupy one or more blocks.
Usually, each System can be assigned a System Quick Key, to provide easy access to enable the System to be scanned. If the scanner implements Sites to be programmed for a System, usually each site may be programmed with a Site Quick Key. Likewise, Groups can usually be assigned a Group Key Quick.
The number of memory blocks varies by scanner. The allowable number of Systems, Groups within a System, and Channels/Talkgroups within a Group also vary by scanner model.
