摘要

A method and computer program product for freeing memory in a device with limited memory. A plurality of pen strokes is entered into the device, each of which is associated with one of a plurality of logical pages. Each pen stroke is stored in electronic form in the memory in association with its logical page and a recording time. According to the method, memory is freed by all the pen strokes associated with a specific logical page being deleted. The specific logical page is determined on the basis of a time at which a pen stoke associated with the logical page was recorded bz the device. The specific logical page may be determined on the basis of its most recently recorded pen stroke having been recorded earlier than the most recently recorded pen stroke of any of the other logical pages. Alternatively, specific logical page may be determined by a pen stroke associated with the specific logical page having been recorded prior to a predetermined time.
