DESCRIPTION:
• IDT7006 easily expands data bus width to 16 bits or
more using the Master/Slave select when cascading
more than one device
• M/S = H for BUSY output flag on Master,
M/S = L for BUSY input on Slave
• Busy and Interrupt Flags
The IDT7006 is a high-speed 16K x 8 Dual-Port Static
RAM. The IDT7006 is designed to be used as a stand-alone
Dual-Port RAM or as a combination MASTER/SLAVE Dual-
Port RAM for 16-bit-or-more word systems. Using the IDT
MASTER/SLAVE Dual-Port RAM approach in 16-bit or wider
