Test Mode
As the HYB 314405BJ/BT is organized internally as 512 K x 8-bits, a test mode cycle using 8:1
compression can be used to improve test time. Note that in the 1 M x 4 version the test time is
reduced by 1/2 for a linear test pattern.
In a test mode “write” the data from each I/O1 pin is written into eight bits simultaneously (all “1” s
or all “0” s). The I/O2-I/O4 inputs are not used for writing in test mode. In test mode “read” each I/O
output is used for indicating the test mode result. If the internal eight bits are equal, the I/O would
indicate a “1”. If they were not equal, the I/O would indicate a “0”. Note that in test mode read“ I/
O1-I/O3 are always driven to ones“, i.e. all outputs will be 1“s for a test mode pass“. The WCBR
cycle (WE, CAS before RAS) puts the device into test mode. To exit from test mode, a “CAS before
RAS refresh”, “RAS only refresh” or “Hidden refresh” can be used.
Addresses A10R, A10C and A0C are don‘t care during test mode.
