HYMA6V8730E18HGTG
8Mx72 buffered EDO DRAM DIMM
PRELIMINARY
Description
The HYMA6V8730E18HGTG familiy is an 8Mx72 bits Dynamic RAM Module which is assembled 9 pieces of 8Mx8bit
DRAMs in 32pin TSOP-II package and two 16bit driver ICs in 48pin TTSOP package mounted on a 168pin printed cir-
cuit board with decoupling capacitors.
The HYMA6V8730E18HGTG is optimized for application to the systems which are required high density and large
capacity such as main memory of the computers and an image memory systems, and to the others which are
requested compact size.
The HYMA6V8730E18HGTG provides common data inputs and extended data outputs
