16 Mb Chip organised as: 4M x 4 bits 2K refresh, Fast Page Mode (FPM) Speed = 60ns, Supply = 5 Volt |
How do I read the type number?

^^----------------- HY = Hyundai
HY514400-60
^^^-------------- 514 = 4 Megabit chip
511 = 16 Megabit chip: see below
531 = 1 Megabit chip
534 = 1 Megabit chip
53C = 256 Kilobit chip
HY514400-60
^^^----------- Internal Organization & Refresh:
100 = 4Meg x 1 / ?? refresh
260 = 256K x 16 / 512 refresh
400 = 1Meg x 4 / 1K refresh
800 = 512K x 8 / 1K refresh
