PIN DESCRIPTION
DESCRIPTION
Pin name
Function
This is a family of 4194304-word by 4-bit dynamic RAMS,
fabricated with the high performance CMOS process, and is ideal
for large-capacity memory systems where high speed, low power
dissipation, and low costs are essential.

The use of double-layer metal process combined with twin-well
CMOS technology and a single-transistor dynamic storage stacked
capacitor cell provide high circuit density at reduced costs.
Multiplexed address inputs permit both a reduction in pins and an
increase in system densities.

FUNCTION
The M5M417400CJ,TP provide, in addition to normal read, write, and read-modify-write operations, a number of other functions, e.g., fast
page mode, RAS-only refresh, and delayed-write. The input conditions for each are shown in Table 1.

Note 5: An initial pause of 500 µ s is required after power-up followed by a minimum of eight initialization RAS cycles. The initialization cycles should be done either by RAS-only
refresh cycles or by CAS before RAS refresh cycles only.
Note the RAS may be cycled during the initial pause. And any 8 RAS or RAS/CAS cycles are required after prolonged periods (greater than 32ms) of RAS inactivity before
proper device operation is achieved.
After the initialization cycles, RAS should be kept either higher than V

Self refresh devices are denoted by “S” after speed item, like -5S/-6S/-7S. The other characteristics and requirements than the below are
same as normal devices.

Note 27: The test mode function is initiated by a W and CAS before RAS cycle (WCBR cycle) as specified in timing diagram.
The test mode function is terminated by either a CAS before RAS refresh cycle (CBR refresh cycle) or a RAS only refresh cycle.
During the test mode, the device is internally organized as 16-bits wide (1M bytes depth). No addressing of CA and CA is required.

During a write cycle, data must be applied to all DQ (input) pins. The data can be different between DQ pins. The data on each DQ pin is written into 4-bits memory cells,
respectively. During a read cycle, each DQ (output) pin shows the test result of the 4-bits, respectively. High state indicates that they are same. Low state indicates that they
are not same.
During the test mode operation, only WCBR cycle can be used to perform refresh.
