Interface socket design methodology to generate embedded DRAM macros

A new design methodology for embedded DRAM is introduced. The DRAM macro consists of common DRAM core and interface socket. Splitting the DRAM macro into common DRAM core and interface socket widens the reconfigurability of the functions of the macro. An experimental chip consists of 12M-bit DRAM core and synchronous interface socket was developed with 0.18 /spl mu/m technology.
