This document introduces a semiconductor product, which is a 4M x 32-bit or 8M x 16-bit dynamic RAM module. The module features fast access and cycle time, fast page mode capability, low power dissipation, CAS-before-RAS refresh, etc.
The Siemens HYM 324020S/GS-50/-60 is a 4M x 32-Bit Dynamic RAM module organized as 4,194,304 words by 32-bit. It is a 72-pin Single In-Line Memory Module (SIMM) that utilizes eight 4M x 4 DRAMs in 300mil wide SOJ packages mounted on a PCB with eight 0.2 uF ceramic decoupling capacitors. The module supports both 50 ns and 60 ns access time versions and is optimized for byte-write non-parity applications.
