[GTALUG] Write Only Memory

[James Knott]

The Signetics 25000 Series 9C46XN Random Access Write-
Only-Memory employs both enhancement and depletion mode
P-Channel, N-Channel and Neu¹ channel MOS devices.
Although a static device, a single TTL level clock phase is
required to drive the on-board multi-port clock generator. Data
refresh is accomplished during CB and LH periods. Quadri-
state outputs (when applicable) allow expansion in many
directions, depending on organization.
