GENERAL DESCRIPTION
are not used internally. As for low 16 bit address, A1~A8
are through 8 bit address counter, A9~A15 are through 7
bit address register, and A0 are not used internally. High
address input must be done before low address input,
and both address inputs are needed for page change or
address change in a same page. After address inputs,
CE goes high at ALEH falling edge and RD doesn't toggle,
the ROM is in stand-by mode.
The product is a 64M bits (4M x 16) mask ROM
composed of 16K pages, and each consists of 256 words
memory cell array. This mask ROM has a 16 bit address
input / data output bus (AD0~AD15), two address latch
enable pins (high : ALEH, low : ALEL), a read strobe
(RD).
There are 3 modes, Stand-by mode, Active mode, and
Address input mode. Stand-by mode is a non-operating
state, and has the smallest current dissipation. Active
mode is an operating state, and data output is possible.
Address input mode is a state of address input.
After ROM turned into Active mode from Address input
mode, it takes tL time to read. In a page, sequential
read access is possible at tCYC cycle time. Sequential
read operation (increment of internal address counter) is
done at every falling edge of RD. At the end of a page,
internal address counter raps around to the beginning of
the page.
Address input is through AD bus when ALEL is high.
The high and low 16 bit addresses are latched at
ALEH’sand ALEL falling edges. As for high 16 bit ad-
dress, A0~A6 are through 7 bit address register, A7~A15
