16Mx64 bits PC100 SDRAM SO DIMM based on 16Mx16 SDRAM with LVTTL, 4 banks & 8K Refresh HYM72V16M656T6 Series DESCRIPTION The HYM72V16M656T6 -Series are high speed 3.3-Volt Synchronous DRAM Modules composed of four 16Mx16 bit Synchronous DRAMs in 54-pin TSOPII and 8-pin TSSOP 2K bit EEPROM on a 144-pin Zig Zag Dual pin glass-epoxy printed circuit board. Three 0.1uF decoupling capacitors per each SDRAM are mounted on the module. The HYM72V16M656T6 -Series are gold plated socket type Dual In-line Memory Modules suitable for easy interchange and addition of 128M bytes memory. 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.
