70261 - Block Diagram
Description
The 70261 is a high-speed 16K x 16 Dual-Port Static RAM designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word systems. An automatic power down feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.

Confirm Memory Address Capacity 7025L20PFGI
Hi, I would like to confirm whether the memory size of 8Kx16 for the 7025L20PFGI means there are only 8,000 memory addresses, or does it go up to 8,192? If there are only 8,000 memory addresses, I have also found the 16Kx16 version online, which does not ...
