HB56UW464EJN-6B/7B

4,194,304-word

64-bit High Density Dynamic RAM Module

168-pin JEDEC Standard Outline Unbufferd 8 byte DIMM

ADE-203-594(Z)

Preliminary- Rev. 0.0

May. 15, 1996

Description

The HB56UW464EJN belongs to 8 Byte DIMM (Dual In-line Memory Module) family, and has been

developed as an optimized main memory solution for 4 and 8 Byte processor applications.

The HB56UW464EJN is a 4M

64 dynamic RAM module, mounted 16 pieces of 16-Mbit DRAM

(HM51W16405BJ) sealed in SOJ package and 1 piece of serial EEPROM (24C02) for Presence Detect

(PD). The HB56UW464EJN offers Extended Data Out (EDO) Page Mode as a high speed access mode.

An outline of the HB56UW464EJN is 168-pin socket type package (dual lead out). Therefore, the

HB56UW464EJN makes high density mounting possible without surface mount technology. The

HB56UW464EJN provides common data inputs and outputs. Decoupling capacitors are mounted beneath

each SOJ on the module board.
