DESCRIPTION
The ISSI IS61/64WV102416EDALL/EDBLL are high-speed,
low power, 16M bit static RAMs organized as 1M words by
16 bits. It is fabricated using ISSI's high-performance CMOS
technology and implemented ECC function to improve
reliability.
This highly reliable process coupled with innovative circuit
design techniques including ECC (SEC-DED: Single Error
Correcting-Double Error Detecting) yield high-performance
and highly reliable devices.
When CS# is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be
reduced down with CMOS input levels. Easy memory
expansion is provided by using Chip Enable and Output
Enable inputs.
The active LOW Write Enable (WE#) controls both writing
and reading of the memory. A data byte allows Upper Byte
(UB#) and Lower Byte (LB#) access.
The IS61/64WV102416EDALL/EDBLL are packaged in the
JEDEC standard 48-pin mini BGA (6mm x 8mm), and 48-pin
TSOP (TYPE I)
