184pin Registered DDR SDRAM DIMMs based on 256Mb D ver. (TSOP)
This Hynix Registered Dual In-Line Memory Module (DIMM) series consists of 256Mb D ver. DDR SDRAMs in 400mil.
TSOP II packages on a 184pin glass-epoxy substrate. This Hynix 256Mb D ver. based Registered DIMM series provide
a high performance 8-byte interface in 5.25" width form factor of industry standard. It is suitable for easy interchange
and addition.
