Utilizing the Page Mode Am29PDS32x for Maximum Performance
2
Table 2.
Access Times
As the table clearly shows, the Am29PDS322 performs
four read operations 38% faster than the standard flash
device.
IMPROVED POWER CONSUMPTION AND
ENERGY CONSUMPTION
The Am29PDS32x devices can reduce power in two
ways. First, by reducing the time power must be at the
higher active read consumption level. Second, by re-
ducing the active read current requirement following
the initial access time, such that the average power for
a series of page reads is lower. A random access read
operation consumes 16 mA at 10 MHz. However, once
the page has been initially accessed, each subsequent
page read only uses 2.5 mA at 20 MHz.
By looking at an example comparing the Am29PDS322
and a standard flash device, the power consumption
difference can clearly be seen. Table 3 compares the
Am29SL160 device which consumes 8 mA at 10 MHz
for a random access read, and the Am29PDS322
which also consumes 16 mA at 10 MHz for a random
access read, but consumes 2.5 mA for an intra-page
read. This example shows the average power con-
sumed for each device to read four consecutive words.
Table 3.
Average Power Consumed To Read
Four Words
This table shows that the Page Mode device consumes
27% less power than a standard flash device to read
four words.
In addition to the lower average power, the
Am29PDS322 is also active for a shorter amount of
time. As stated before, the Am29SL160 would have to
consume 8 mA for 400 ns, whereas the Am29PDS322
is only active for 250 ns. This means that the Page
Mode device consumes less average power, and for a
shorter amount of time. This leads to lower energy con-
sumption. Figure 1 compares the power consumption
and energy consumption of the Am29SL160 and the
Am29PDS322
.
