HB56A840BR Series 8,388,608-word × 40-bit High Density Dynamic RAM Module ADE-203Rev. 0.0 Dec. 1, 1995 Description The HB56A840BR is a 8 M × 40 dynamic RAM module, mounted 20 pieces of 16-Mbit DRAM (HM5116400BS) sealed in SOJ package. An outline of the HB56A840BR is 72-pin single in-line package. Therefore, the HB56A840BR makes high density mounting possible without surface mount technology. The HB56A840BR provides common data inputs and outputs. Decoupling capacitors are mounted beneath each SOJ only on the one side its module board.
