The IDT7133/7143 are high-speed 2K x 16 Dual-Port Static RAMs.
The IDT7133 is designed to be used as a stand-alone 16-bit Dual-Port
RAMor as a “MASTER” Dual-Port RAMtogether with the IDT7143
“SLAVE” Dual-Port in 32-bit-or-more word width systems. Using the
IDT MASTER/SLAVE Dual-Port RAMapproach in 32-bit-or-wider
