Description
The AT27LV1026 is a high performance 16-bit interleaved low-voltage 1,048,576-bit
one-time programmable read only memory (OTP EPROM) organized as 2 x 32K x 16
bits. It requires only one supply in the range of 3.0V to 3.6V in normal read mode
operation.

... LA cycle will be terminated when CS is asserted high put- ting the device in standby mode, or another NLA cycle starts. The LA cycle can be resumed when CS is asserted low and ALE stays low. The AT27LV1026 will continuously output data within each LA cycle which is determined by the read RD signal. Continuous interleave read operation is possible as there is no physical limit to the linear access LA output ...
