Notes: 1. A start-up delay of 200 µs is required after power-up, followed by a minimum of eight
initialization cycles (RAS-only refresh or CAS before RAS refresh) before proper device
operation is achieved.

10. These parameters are referenced to the CAS leading edge in an early write cycle, and
to the WE leading edge in an OE control write cycle, or a read modify write cycle.
11. The test mode is initiated by performing a WE and CAS before RAS refresh cycle.
This mode is latched and remains in effect until the exit cycle is generated.
The test mode specified in this data sheet is a 2-bit parallel test function. CA8 is not
used. In a read cycle, if all internal bits are equal, the DQ pin will indicate a high
level. If any internal bits are not equal, the DQ pin will indicate a low level.
The test mode is cleared and the memory device returned to its normal operating
state by performing a RAS-only refresh cycle or a CAS before RAS refresh cycle.
12. In a test mode read cycle, the value of access time parameters is delayed for 5 ns for the
specifiedvalue.Theseparametersshouldbespecifiedintestmodecyclebyaddingthe
above value to the specified value in this data sheet.

Notes for Mounting the Surface Mount Type Package
The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which
are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki’s responsible sales person for the
product name, package name, pin number, package code and desired mounting conditions
(reflow method, temperature and times).
