Burst Data Interruption U/LDQM Pins (Write
Cycle)
Burst data input can be temporarily interrupted (muted )
during a write cycle using the U/LDQM pins. Regardless of
the
CAS
latency, as soon as one of the U/LDQM pins goes
HIGH, the corresponding externally applied input data will
no longer be written to the device internal circuits.
Subsequently, the corresponding input continues to be
muted as long as that U/LDQM pin remains HIGH.
The IS42VS16100C1 will revert to accepting input as soon
as
that pin is dropped to LOW and data will be written to the
device. This input control operates independently on a byte
basis with the UDQM pin controlling upper byte input (pin
DQ8 to DQ15) and the LDQM pin controlling the lower byte
input (pins DQ0 to DQ7).
Since the U/LDQM pins control the device input buffers
only, the cycle continues internally and, in particular,
incrementing of the internal burst counter continues.
Burst Read and Single Write
The burst read and single write mode is set up using the
mode register set command. During this operation, the
burst read cycle operates normally, but the write cycle only
writes a single data item for each write cycle. The
CAS
latency and DQM latency are the same as in normal mode.
