Abstract
The improved memory system can use various memories, such as CCDs and RAMs. Adaptive memory capability and memory servo capability improve memory characteristics. In a RAM embodiment, a detector is used to detect a memory address condition and to control the memory and the memory address register in response thereto. In a CCD embodiment, a detector is used to detect a memory reference signal and to refresh the memory signals in response thereto. Improved memory refresh, memory performance, and memory capacity enhance system characteristics. Improved memory architecture provides advantages of increased speed, lower cost, and efficiency of implementation. Information stored in memory can be scanned out at a rate greater than the addressing rate associated with the memories. This permits higher speed operation with lower cost memories. Use of an output buffer, such as a FIFO, permits normalization of memory clock rates.
