3.3 V OPERATION 16 M-BIT DYNAMIC RAM
1 M-WORD BY 16-BIT, EDO, BYTE READ/WRITE MODE
MOS INTEGRATED CIRCUIT
μ
PD42S18165L, 4218165L
Description
The
μ
PD42S18165L, 4218165L are 1,048,576 words by 16 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
PD42S18165L can execute CAS before RAS self refresh.
The
μ
PD42S18165L, 4218165L are packaged in 50-pin plastic TSOP (
II
) and 42-pin plastic SOJ.
