CAMERA PHONE MEMORY SNAPS IN PLACE

摘要

Three main factors drive memory choice: high capacity, high performance and high reliability High-resolution images, multi-shot photography and video strain memory capacity and performance perhaps more than any other phone activity today. Early camera phones did not always offer sufficient storage for pictures or video. Today they will typically be required to store around 100 pictures and 10 minutes of video, which significantly impacts storage requirements (see tables 1 and 2]. As camera phones start to feature 1 Mpixel cameras and upwards, they will require between 50 to 100MByte or more of user storage. Sub-second shots, multi-shot features and 'unlimited' streaming video (limited only by the size of the flash and not by the size of the RAM) require 1 MByte/sec sustained write performance.
