A clear freeze frame does not explicitly require digital memory at all. Sony did it in 1981 with their SL-5800, using dual-azimuth video heads.
Pioneer sold its first Laser Disc player with digital video memory in 1988-89, the CLD-3030. That machine only stored one field of NTSC video, so that is an indication of the cost of memory at that time.
It also may be that just storing frames/fields of video is a lot simpler than actually manipulating that memory as needed for time-base correction. That level of information is beyond my knowledge.
