DESCRIPTION

The TC511000P/J/Z is the new generation dynamic

RAM organized 1,048,576 words by 1 bit. The

TC511000P/J/Z 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

TC511000P/J/Z 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 performance logic

families such as Schottky TTL. Test Mode function is

implemented from Revision C.
