512 MB Unbuffered SDRAM S.O.DIMM 64-Mword × 64-bit, 133/100 MHz Memory Bus, 2-Bank Module (16 pcs of 32 M × 8 components) PC133/100 SDRAM
E0083H40 (Ver. 4.0) Nov. 16, 2001 (K) Japan Description
The HB52RF648DC, HB52RD648DC are a 32M × 64 × 2 banks Synchronous Dynamic RAM Small Outline Dual In-line Memory Module (S.O.DIMM), mounted 16 pieces of 256-Mbit SDRAM (HM5225805BTB) sealed in TCP package and 1 piece of serial EEPROM (2-kbit) for Presence Detect (PD). An outline of the products is 144-pin Zig Zag Dual tabs socket type compact and thin package. Therefore, they make high density mounting possible without surface mount technology. They provide common data inputs and outputs. Decoupling capacitors are mounted beside TCP on the module board.
