The GLT44108 is a 524,288 x 8 bit high-
performance
CMOS
dynamic
random
access
memory. The GLT44108 offers Fast Page mode with
asymmetric address and accepts 512-cycle refresh in
8ms interval.
All inputs are TTL compatible. Fast Page Mode
operation allows random access up to 512 x 8 bits
within a page, with cycle times as short as 22ns.
The GLT44108 is best suited for graphics, digital
signal processing and high performance peripherals.
