Abstract
An acquisition/playback device and a memory device including a solid-state write-once memory array are used to acquire and display digital information such as digital images, voice, music, or the like. Prior to display or other presentation, the digital information is stored in a re-writable memory. After the digital information has been displayed or otherwise presented to the user for review, the user then elects whether to store the digital information in the write-once memory array. Depending upon the user election, the digital information is either stored in the write-once memory array, or erased from the re-writable memory without being stored in the write-once memory array. In this way the limited storage capacity of the write-once memory array is preserved for digital information that is of long-term interest to the user. Similarly, an acquisition/playback device itself can review the digital information stored in the re-writable memory and determine whether to commit that file to the write-once memory or to discard the file from the re-writable memory.
