Description
The HB56SW1664DBD is a 16M
×
64 dynamic RAM Small Outline Dual In-line Memory Module
(S.O.DIMM), mounted 16 pieces of 64-Mbit DRAM (HM5164405A) sealed in TCP package and 1 piece of
serial EEPROM (2-kbit) for Presence Detect (PD). The HB56SW1664DBC is a 16M

64 dynamic RAM
Small Outline Dual In-line Memory Module (S.O.DIMM), mounted 16 pieces of 64-Mbit DRAM
(HM5165405A) sealed in TCP package and 1 piece of serial EEPROM (2-kbit) for Presence Detect (PD).
The HB56SW1664DBD, HB56SW1664DBC offer Extended Data Out (EDO) Page Mode as a high speed
access mode. An outline of the HB56SW1664DBD, HB56SW1664DBC is 144-pin Zig Zag Dual tabs
socket type compact and thin package. Therefore, the HB56SW1664DBD, HB56SW1664DBC make high
density mounting possible without surface mount technology.
The HB56SW1664DBD,
HB56SW1664DBC provide common data inputs and outputs. Decoupling capacitors are mounted on the
module board.
