64Mx64bits PC133 SDRAM SO DIMM
based on 32Mx8 SDRAM with LVTTL, 4 banks & 8K Refresh
HYM72V64M636B(L)F Series
DESCRIPTION
Preliminary
The HYM72V64M636B(L)F8 is 64Mx64bits Synchronous DRAM Modules. The modules are composed of sixteen 32Mx8bits CMOS Synchronous DRAMs in FBGA package, one 2Kbit EEPROM in 8pin TSOP package on a 144pin glass-epoxy printed circuit board. One 0.1uF decoupling capacitor is mounted on the printed circuit board in parallel for each SDRAM. The HYM72V64M636B(L)F8 is Small Outline Dual In-line Memory Modules suitable for easy interchange and addition of 512Mbytes memory. The HYM72V64M636B(L)F8 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.
