128Mx72 bits
PC100 SDRAM Registered DIMM
with PLL, based on 64Mx4 SDRAM with LVTTL, 4 banks & 8K Refresh
HYM72V12C756K4 Series
DESCRIPTION
The HYM72V12C756K4 Series are 128Mx72bits ECC Synchronous DRAM Modules. The modules are composed of thirty six
64Mx4bits CMOS Synchronous DRAMs in 400mil 54pin TSOP-II stack package, one 2Kbit EEPROM in 8pin TSSOP package on a
168pin glass-epoxy printed circuit board. One 0.22uF and one 0.0022uF decoupling capacitors per each SDRAM are mounted on the
PCB.
The HYM72V12C756K4 Series are Dual In-line Memory Modules suitable for easy interchange and addition of 1Gbytes memory. The
HYM72V12C756K4 Series are fully synchronous operation referenced to the positive edge of the clock . All inputs and outputs are
synchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve very high bandwidth.
