HB56D136 Series
1,048,576-word × 36-bit High Density Dynamic RAM Module
ADE-203-209A (Z) Rev 1.0
Sept. 20, 1994
Description
The HB56D136 is a 1-M × 36-bit dynamic RAM module, mounted 8 pieces of 4 Mbit DRAM (HM514400CS/CLS) sealed in SOJ package and 2 pieces of 2 Mbit DRAM (HM512200BS/BLS) sealed in SOJ package. An outline of the HB56D136 is 72-pin single in-line package.
Therefore, the HB56D136 makes high density mounting possible without surface mount technology. The HB56D136 provides common data inputs and outputs. Decoupling capacitors are mounted beneath each SOJ.
