DESCRIPTION

operations.

The HY29F400A is an 4 Megabit, 5.0 volt-only CMOS

Flash memory device organized as a 512 Kbytes of 8-

bits each, or 256 Kbytes of 16 bits each. The device

is offered in standard 44-pin PSOP and 48-pin

TSOP packages. It is designed to be programmed

and erased in-system with a 5.0 volt power-supply

and can also be programmed in standard PROM

programmers.

The HY29F400A is programmed by executing the

program command sequence. This will start the

internal byte/word programming algorithm that

automatically times the program pulse widths

and also verifies proper cell margin. Erase is ac-

complished by executing either the sector erase

or chip erase command sequence. This will start

the internal erasing algorithm that automatically

times the erase pulse width and also verifies

proper cell margin. No preprogramming is re-

quired prior to execution of the internal erase al-

gorithm. Sectors of the HY29F400A Flash

memory array are electrically erased via Fowler-

Nordheim tunneling. Bytes/words are pro-

grammed one byte/word at a time using a hot

electron injection mechanism.

With access times of 45ns, 55ns, 70ns, 90 ns, 120

ns and 150 ns, the HY29F400A has separate chip

enable (/CE), write eable (/WE), and output enable (/

OE) controls. Hyundai Flash memory devices re-

liably store memory data even after 100,000 pro-

gram/erase cycles.

The HY29F400A is entirely pin and command set

compatible with the JEDEC standard for 4Mega-

bit Flash memory devices. Commands are writ-

ten to the command register using standard mi-

croprocessor write timings. Register contents

serve as input to an internal state-machine that

controls the erase and programming circuitry.

Write cycles also internally latch addresses and

data needed for the programming and erase

The HY29F400A features a sector erase architec-

ture. The device memory array is divided into one

16 Kbytes, two 8 Kbytes, one 32 Kbytes, and

seven 64 Kbytes. Sectors can be erased indi-

vidually or in groups without affecting the data in

other sectors. Multiple sector erase and full chip
