Description
The
μ
PD4264405, 42S65405, 4265405 are 16,777,216 words by 4 bits CMOS dynamic RAMs with optional EDO.
EDO is a kind of the page mode and is useful for the read operation.
Besides, the
μ
PD42S65405 can execute CAS before RAS self refresh.
These are packaged in 32-pin plastic TSOP (II) and 32-pin plastic SOJ.
