DESCRIPTION

The TC511001AP/AJ/AZ is the new generation dynamic RAM organized 1,048,576 words by

1 bit. The TC511001AP/AJ/AZ utilizes TOSHIBA's CMOS Silicon gate process technology as

well as advanced circuit techniques to provide wide operating margins, both internally

and to the system user. Multiplexed address inputs permit the TC511001AP/AJ/AZ to be

packaged in a standard 18 pin plastic DIP, 26/20 pin plastic SOJ and 20/19 pin plastic

ZIP. The package size provides high system bit densities and is compatible with widely

available automated testing and insertion equipment. System oriented features include

single power supply of 5V±10 tolerance, direct interfacing capability with high perform-

ance logic families such as Schottky TTL. The special feature of TC511001AP/AJ/AZ is

nibble mode, allowing the user to serially access 4 bits of data at a high data rate.
