The first one seems to be PC133 SDRAM that's rated at CAS latency 3 at 133MHz. The memory chips appear to be rated at a 7.5ns clock period, which is normal for PC133 SDRAM. I can't tell the manufacturer/brand from the markings. As for the 128MB one, its obviously a PC100 module and appears to be rated at an 8ns clock period, which is normal for PC100 SDRAM. The manufacturer is unknown to me too.
