How a nand gate decoder is used for 2716 eprom memory, Electrical Engineering

Assignment Help:

With neat diagram indicate how a simple NAND gate decoder is used to select a 2716 EPROM memory component for memory locations FF800H-FFFFFH.

Simple NAND gate Decoder: As the 2k x 8 EPROM is utilized, address connection A10 to A0 of the 8088 are attached to address inputs A10 to A0 of the EPROM. The waiting nine address pins (A19 to A11) are attached to the inputs of a NAND gate decoder. This decoder selects the EPROM from one of a lot of 2Kbyte sections of the entire 1Megha byte address range of 8088 microprocessor.

A simple NAND decoder is used to select a 2716 EPROM memory component.

In circuit of a single NAND gate, it decodes the memory address. There output of the NAND gate is logic 0 when the 8088 address pins connected to its inputs (A19-A11) are all logic one's. This active low, logic 0 output of the NAND gate decoder is attached to the CE' input pin that chooses (enables) the EPROM.
