Abstract
A pager which does not delete or rewrite received messages can be produced at such a low cost that it is viable as a disposable pager. Messages are stored sequentially as they are received, packed in memory end-to-end, so that memory efficiency is maximized. No complex memory management is required, minimizing production costs. If memory is full or near-full when a new message is received, either the message is displayed and not stored, or receipt of the new message is refused. By using removable, nonvolatile memory modules, the pager unit can be reused, while enabling old messages to be externally archived for indefinite periods of time.
