Gate array arrangement in complementary metal-oxide-semiconductor

Abstract

A gate array arrangement provides cell zones in the form of a matrix in a core zone of a chip. Each cell zone contains a fundamental circuit which consists of six or seven transistors designed in CMOS technology and which can perform a logic function or a storage function on the basis of appropriate interconnections. The connection of the fundamental circuits to one another is carried out either by way of the fundamental circuits or by using fundamental circuits which are not used to construct memories or logic functions. On the basis of the fundamental circuits consisting of six or seven n-channel and p-channel transistors it is possible to construct one storage cell per fundamental circuit and therefore to provide memories which can be adapted to the prevailing requirements in a gate array arrangement.
