The MSM548331 is a 2.7-Mbit, 768 bits ¥ 290 lines, Field Memory. Access is done line by line. The line
address must be set each time a line is changed.
More than two MSM548331s can be cascaded directly without any delay devices between them.
Cascading MSM548331s provides larger capacity and longer delay.
X serial address input enables random initial address setting of serial access in a page. Other than the
random address setting, MSM548331 has several types of address set modes such as line hold,
address jump to initial address and line increment.
though it contains dynamic type memory cells. MSM548331 has write mask function or input enable
function (IE), and read-data skipping function or output enable function (OE).
The MSM548331 is especially designed for digital TVs and VTRs for consumer use and video
The MSM548331 is not designed for high end use in such applications as medical systems,
professional graphics systems which require long term picture storage, data storage systems and
