The Samsung KMM372C80(8)3C consists of nine CMOS 8Mx8bits DRAMs in SOJ/TSOP-II 400mil packages and two 16 bits driver IC in TSSOP package mounted on a 168-pin glass-epoxy sub- strate. A 0.1 or 0.22uF decoupling capacitor is mounted on the printed circuit board for each DRAM. The KMM372C80(8)3C is a Dual In-line Memory Module and is intended for mounting into 168 pin edge connector sockets. GENERAL DESCRIPTION PD Note :PD & ID Terminals must each be pulled up through a resistor to VCC at the next higher level assembly. PDs will be either open (NC) or driven to VSS via on-board buffer circuits. ID Note : IDs will be either open (NC) or connected directly to VSS without a buffer. • Part Identification • Fast Page Mode Operation • CAS-before-RAS Refresh capability • RAS-only and Hidden refresh capability • TTL compatible inputs and outputs • Single 5V ±10% power supply • JEDEC standard pinout & Buffered PDpin • Buffered input except RAS and DQ • PCB : Height(1250mil), single sided component Part number PKG Ref.
