삼성 램 번호 읽는 법
KM 4 xx S xx x x x x x - x xx
1 2 3 4 5 6 7 8 9 10 11 12
1 = SAMSUNG MEMORY
2 = DRAM
3 = ORGANIZATION : 4 = x4 , 8 = x8 , 16 = x16
4 = FEATURE : S = SDRAM
5 = DENSITY : 1 = 1M ,2 = 2M ,4 = 4M ,8 = 8M ,16 = 16M
6 = REFRESH : 0 = 4K , 1 = 2K , 2 = 8K
7 = NUMBER OF BANKS : 2 = 2 Banks , 3 = 4 Banks
8 = INTERFACE : 0 = LVTTL , 1 = SSTL
9 = REVISION : Blank = 1st , A = 2nd , B = 3rd
10 = PACKAGE : T = TSOP II (400mil)
11 = POWER : G = Auto & Self-Refresh ,
F = Auto & Self-Refresh
w/Low Power
12 = MIN. CYCLE TIME(Max. Frequency)
7 = 7ns(143MHz)
8 = 8ns(125 MHz)
10 = 10ns(100 MHz)
H = 100 MHz @ CL-2
L = 100 MHz @ CL-3
(참고 CL = Cycle Length)
